ESA’s XMM-Newton space telescope has helped to identify a star and a black hole that orbit each other at the dizzying rate of once every 2.4 hours, smashing the previous record by nearly an hour.The black hole in this compact pairing, known as MAXI J1659-152, is at least three times more massive than the Sun, while its red dwarf companion star has a mass only 20% that of the Sun. The pair is separated by roughly a million kilometres.The duo were discovered on 25 September 2010 by NASA’s Swift space telescope and were initially thought to be a gamma-ray burst. Later that day, Japan’s MAXI telescope on the International Space Station found a bright X-ray source at the same place.
More observations from ground and space telescopes, including XMM-Newton, revealed that the X-rays come from a black hole feeding off material ripped from a tiny companion.
Several regularly-spaced dips in the emission were seen in an uninterrupted 14.5 hour observation with XMM-Newton, caused by the uneven rim of the black hole’s accretion disc briefly obscuring the X-rays as the system rotates, its disc almost edge-on along XMM-Newton’s line of sight.
From these dips, an orbital period of just 2.4 hours was measured, setting a new record for black hole X-ray binary systems. The previous record-holder, Swift J1753.5–0127, has a period of 3.2 hours.
The black hole and the star orbit their common centre of mass. Because the star is the lighter object, it lies further from this point and has to travel around its larger orbit at a breakneck speed of two million kilometres per hour – it is the fastest moving star ever seen in an X-ray binary system. On the other hand, the black hole orbits at ‘only’ 150 000 km/h.
“The companion star revolves around the common centre of mass at a dizzying rate, almost 20 times faster than Earth orbits the Sun. You really wouldn’t like to be on such a merry-go-round in this Galactic fair!” says lead author Erik Kuulkers of ESA’s European Space Astronomy Centre in Spain.
His team also saw that they lie high above the Galactic plane, out of the main disc of our spiral Galaxy, an unusual characteristic shared only by two other black-hole binary systems, including Swift J1753.5–0127.
“These high galactic latitude locations and short orbital periods are signatures of a potential new class of binary system, objects that may have been kicked out of the Galactic plane during the explosive formation of the black hole itself,” says Dr Kuulkers.
Returning to MAXI J1659−152, the quick response of XMM-Newton was key in being able to measure the remarkably short orbital period of the system.
“Observations started at tea-time, just five hours after we received the request to begin taking measurements, and continued until breakfast the next day. Without this rapid response it would not have been possible to discover the fastest rotation yet known for any binary system with a black hole,” adds Norbert Schartel, ESA’s XMM-Newton project scientist.
A black hole is formed when a star implodes with enough force to overcome the nuclear strong force. If the neutron core of a supernova is greater than about 2 solar masses, the core will collapse into a black hole.
Structure of a black hole:
-The photon sphere traps light particles in orbit around the black hole
-Inside the event horizon light particles cannot escape
-The event horizon’s diameter is 6 km for every 1 solar mass the black hole contains
- Gravitational lensing of background stars occurs out to a distance twice the radius of the event horizon
X-ray binaries may be black holes pulling material from their companion stars. Cygnus X-1 may be a binary star pair containing a black hole.
Gravitation waves from black holes may be detectable and may tell us about the processes occurring during the birth of a black hole.
Asteroid 2012 DA14 Zooms just 17,200 miles above Earth on Feb. 15, 2013 in this artist’s concept: Credit: NASA/JPL
Our home planet is due for a record setting space encounter on Friday (Feb. 15) of this week, when a space rock roughly half a football field wide skirts very close by Earth at break neck speed and well inside the plethora of hugely expensive communications and weather satellites that ring around us in geosynchronous orbit.
“There is no possibility of an Earth impact” by the Near Earth Asteroid (NEO) known as 2012 DA 14, said Don Yeomans, NASA’s foremost asteroid expert at a media briefing. Well that’s good news for us – but a little late for the dinosaurs.
At its closest approach in less than 4 days, the 45 meter (150 feet) wide Asteroid 2012 DA14 will zoom by within an altitude of 27,700 kilometers (17,200 miles). That is some 8000 km (5000 miles) inside the ring of geosynchronous satellites, but far above most Earth orbiting satellites, including the 6 person crew currently working aboard the International Space Station.
Although the likelihood of a satellite collision is extremely remote, NASA is actively working with satellite providers to inform them of the space rocks path.
The razor thin close shave takes place at about 2:24 p.m. EST (11:24 a.m. PST and 1924 UTC) as the asteroid passes swiftly by at a speed of about 7.8 kilometers per second (17,400 MPH)- or about 8 times the speed of a rifle bullet. For some perspective, it will be only about 1/13th of the distance to the moon at its closest.
“Asteroid 2012 DA14 will make a very close Earth approach, traveling rapidly from South to North and be moving at about two full moons per minute,” said Yeomans, who manages NASA’s Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif. “That’s very fast for a celestial object.”

No known asteroid has ever passed so near to Earth.
“This is a record predicted close approach for a known object this size,” stated Yeomans. “Such close flybys happen every 40 years on average. An actual Earth collision would happen about every 1200 years.”
Even though 2012 DA14 is coming remarkably close, it will still only appear as a point of light in the biggest of optical telescopes, because of its small size. Based on its brightness, astronomers estimate that it is only about 45 meters (150 feet) across. It will brighten only to magnitude 7.5, too faint to be seen with the naked eye, but easily visible with a good set of binoculars or a small telescope. The best viewing location for the closest approach will be Indonesia, from which the asteroid will be seen to move at a rate of almost 1 degree per minute against the star background. Eastern Europe, Asia and Australia are also well situated to see the asteroid around its closest approach.
The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so close that it will pass inside the ring of geosynchronous weather and communications satellites.
NASA’s Near-Earth Object Program Office can accurately predict the asteroid’s path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth. Nevertheless, the flyby will provide a unique opportunity for researchers to study a near-Earth object up close.
Asteroid 2012 DA14 will be closest to Earth on Feb. 15, at about 11:24 p.m. PST (2 p.m. EST and 1924 UT), when it will be at a distance of about 27,700 kilometers (17,200 miles) above Earth’s surface.
Although this is close enough for the asteroid to pass inside the ring of geosynchronous satellites, located about 35,800 kilometers (22,200 miles) above the equator, it will still be well above the vast majority of satellites, including the International Space Station.

(Reuters) – Firefighters managed to protect the remaining homes in a southwestern New Mexico subdivision overnight, but some outlying buildings were engulfed by flames from a fire that burned on rough mountain terrain near the Arizona border.
Two fires merged in the Gila National Forest on Thursday and consumed 12,000 additional acres overnight, bringing the total burn area to 82,252 acres with none of it contained, said Public Information Officer Iris Estes.
Estes said firefighters were able to build fire lines toward the north, and expected gusty winds of 15 to 28 miles per hour to move the flames in that direction by midday.
Efforts overnight managed to preserve the more than 45 remaining vacation homes in the area. A total of twelve homes and 13 outlying buildings have been destroyed so far, Estes said.
“The fire is still burning in the subdivision, but they did a good job of getting in there and getting some structure protection in there,” Estes said.
Estes said the fire “spread out and moved in all directions” as it burned late Thursday, which allowed firefighters to get closer to the blaze and build fire lines with bulldozers.
“It didn’t make a run in any one direction, so we’re hoping it will continue to do that today,” she said.
More than 500 people are currently fighting the blaze. Voluntary evacuations were in effect for the nearby town of Mogollon.
May 26 (Reuters) – Subtropical Storm Beryl churned toward the U.S. southeast coast on Saturday, threatening heavy rains and dangerous surf on Sunday to northeastern Florida, Georgia and South Carolina, the U.S. National Hurricane Center said.
Beryl was centered about 230 miles (375 km) east-southeast of Charleston, South Carolina, carrying maximum sustained winds of 45 mph (75 kph). It was moving southwest with tropical storm force winds extending about 115 miles (185 km) from the storm’s center.
Tropical storm warnings were in effect for Sunday from the Volusia/Brevard County line in northern Florida to Edisto Beach, South Carolina.
Forecasters predict the storm will eventually turn back toward the Atlantic on Monday or Tuesday, posing no threat to oil and gas production facilities in the U.S. Gulf of Mexico.
The hurricane center said dangerous surf conditions and unusually high tides are possible along the coasts of northern Florida, Georgia and South Carolina over the Memorial Day weekend.
Beryl is being called a subtropical storm, which usually have a broader wind field than tropical storms and shower and thunderstorm activity farther removed from the storm’s center.
Beryl formed off the South Carolina coast late on Friday and is the second named storm of the Atlantic hurricane season, which has had an early start. The season officially runs from June 1 to Nov. 30. (Reporting by Kevin Gray; Editing by Vicki Allen)
Tokyo soil so contaminated with radiation it would be considered nuclear waste in US
By Ethan A. Huff,
(NaturalNews) Radioactive fallout from the Fukushima Daiichi nuclear disaster continues to show up at dangerously high levels in the city of Tokyo, which is located roughly 200 miles from the actual disaster site. According to an analysis of five random soil samples recently taken by nuclear expert Arnie Gundersen, the soil around Tokyo is so contaminated with Fukushima radiation that it would be considered nuclear waste here in the U.S.
During a recent trip to Tokyo, Gundersen collected soil samples from a sidewalk, a children’s playground, a rooftop, a patch of moss by the side of a road, and the lawn of a judicial building. After sending those samples in for testing, it was revealed that each one had high levels of radioactive cesium-134 (CS134) and cesium-137 (CS137), while three of the samples contained high levels of cobalt-60 (CO60). One of the samples also tested positive for uranium-235 (U235).
“[W]hen I was in Tokyo, I took some samples [...] and sent them to the lab,” said Gundersen in a recent video report. “And the lab determined that all of them would be qualified as radioactive waste here in the United States and would have to be shipped to Texas to be disposed of.”
Despite the fact that radioactive plumes from Fukushima have largely drifted seaward based on wind patterns, a considerable amount of this radiation traveled southward towards Tokyo and elsewhere. The findings also confirm the reality that Fukushima radiation has likely had significant global spread as well, which confirms earlier reports of samples taken on the U.S. West Coast (http://www.naturalnews.com/035731_Fukushima_radiation_America.html).

The next Venus transit across the sun won’t occur until December 2117.

A NASA sun-watching spacecraft will have an unbeatable view of June’s historic Venus transit, but some of the probe’s scientists are taking measures to get a great look for themselves here on Earth, too.
NASA’s Solar Dynamics Observatory (SDO) satellite will watch from space as Venus crosses the sun’s face on June 5 (June 6 in the Eastern Hemisphere) — the last such Venus transit until December 2117. Not content to live vicariously through their spacecraft, some SDO scientists are headed to Alaska to watch the seven-hour event in its entirety.
“For the United States, only Hawaii and Alaska will see the entire transit,” said SDO project scientist Dean Pesnell, of NASA’s Goddard Space Flight Center in Greenbelt, Md. “There’s a solar physics meeting in Anchorage, Alaska, the week after the transit. So we said, ‘Well, let’s go to Alaska and see the transit.’”
Venus transits occur in pairs that are eight years apart, but these dual events take place less than once per century. The last transit happened in 2004, and the next won’t come until 2117. So next month’s transit is the last chance for skywatchers to see Earth’s so-called sister planet trek across the solar disk. [Venus Transit of 2004: 51 Amazing Photos]
Venus transits have played a large role in astronomical history. Scientists and explorers, for example, mounted large expeditions to observe the 18th century’s two transits, which occurred in 1761 and 1769.
The idea was to time the Venus transit precisely from many different spots around the globe, then use the principle of parallax to calculate the distance from Earth to the sun — a quantity that had eluded scientists for millenia. With that information in hand, the scale of the entire solar system would follow.
The 1761 and 1769 efforts both came up short, but measurements made with the help of photographs during the 19th century’s Venus transits finally gave researchers the data they needed.
For its part, SDO will observe the transit to learn more about Venus’ atmosphere and to help calibrate some of its instruments, Pesnell said.
An outreach opportunity
Pesnell and his colleagues plan to watch the transit from Fairbanks, and they’re going to use the rare event as an education and outreach opportunity.
“We’re working with some amateur astronomers up there to set up a family science-oriented event in the city of Fairbanks,” Pesnell told SPACE.com, adding that the team will bring 10 to 20 different displays to teach people about the sun and SDO. “It’s been a fairly popular thing to take to cities.”
Those of us unable to make the trek to Alaska, Hawaii or other good transit-viewing locales around the world will still be able to watch the historic event as it happens. Pesnell said that NASA plans to webcast live footage of the transit from SDO, whose images should be spectacular.
“There are no clouds in space, so we’re guaranteed to have a pretty good view,” Pesnell said.
The $850 million SDO spacecraft launched in February 2010. The probe’s five-year mission is the cornerstone of a NASA science program called Living with a Star, which aims to help researchers better understand aspects of the sun-Earth system that affect our lives and society.

UPCOMING CLOSE APPROACHES TO EARTH

A dead dolphin lying on a beach on the northern coast of Peru, close to Chiclayo, some 750 km north of Lima, in March 2012. Thousands of crustaceans were found dead off the coast of Lima following the mystery mass death of dolphins and pelicans, the Peruvian Navy said Friday
Thousands of crustaceans were found dead off the coast of Lima following the mystery mass death of dolphins and pelicans, the Peruvian Navy said Friday.
The cause of death is under investigation, said Industry and Fishing Minister Gladys Triveno, warning that “it would be premature to give a reason for this phenomenon.”
The Navy said it presented a report on the find to the Agency of Environmental Evaluation and Control to determine the cause.
Biologist Yuri Hooker of Cayetano Heredia University said the species found on Pucusana Beach, 60 kilometers (37 miles) south of Lima, was a type of red krill about three centimeters (1.2 inches) long.
“They live mostly along the coast of Chile up to the coast of northern Peru. What is happening is that these crustaceans are being affected by the warming of Pacific waters in the north of the country,” he said, adding that the phenomenon occurs “with some frequency.”
Hooker explained that the warmer temperatures led the shrimp-like creatures that usually live far away from the coast to move in closer to land, where they died.
Nearly 900 dolphins washed up along Peru’s northern coast between February and April. A government study said the marine mammals died of natural causes, while environmental groups insist the massive toll was linked to offshore oil exploration in the area.
Peruvian officials have suggested that the dolphins, along with 5,000 dead sea birds — mostly pelicans — died due to the effects of rising temperatures in Pacific waters, including the southern migration of fish eaten by the birds.
Hardly a day goes by in Sochi, Russia’s picturesque Black Sea resort, without a dead dolphin washing up on the beach.
With the tourist season just kicking off, the unexplained deaths have yet to draw much scrutiny.
But environmentalists are increasingly alarmed. The dolphin carcasses are also turning into a real holiday spoiler for vacationers drawn to the region’s scenic beaches and pristine vistas.
Russian tourist Aida Kobzh was shocked to discover a group of dead dolphins last week at her local beach in Sochi.
“Everyone stood there and stared at the dead little dolphins lying belly up. Poor creatures!” Kobzh says. “There were some on the beach but also in the water, they were floating there, dead.
Little Official Interest
The dolphins started washing up along Russia’s Black Sea coast several weeks ago. They have also been spotted on Ukrainian shores.
Environmentalists are now talking about the biggest dolphin die-off to date in the region, with an estimated 300 animals dead so far.
Local authorities have made no serious attempt to investigate the deaths, saying the animals are too decayed by the time they reach the shore for laboratory tests to be conducted.
Officials have blamed poachers and fishing nets. They say the unusually cold winter has driven dolphins from the Sea of Azov to the warmer Black Sea.
Some experts, like local zoologist Konstantin Andramonov, point to a possible killer virus.
“The death toll is constantly growing, unfortunately,” Andramonov says. “We are now witnessing the same in Ukraine. There is a hypothesis that we are dealing with an infectious disease that occurs roughly every 20 years.”
Ecosystem In Danger
Most experts, however, believe the real culprit is ever-increasing pollution in the Black Sea region.
Valery Brinikh, who works for the prominent environmental group Ecological Watch, says the scale of the dolphin deaths belies official accounts faulting poachers and fishing nets.
“This happens every year in Sochi — sometimes there are more deaths, sometimes fewer,” Brinikh says. “But the scale this time suggests unnatural causes, probably sea pollution or a loss of orientation of the dolphins, which can also be linked to pollution.”
Environmentalists say pollution levels have risen dramatically around Sochi since the city was selected to host the 2014 Winter Olympic Games.
They have long warned that unbridled construction is inflicting irreparable ecological damage to Sochi’s unique ecosystem.
Olga Noskovets, a local ecologist, suspects that the authorities are perfectly aware it is pollution that is killing the dolphins.
She says pollution levels are highest in areas close to the Olympic construction sites that dot Sochi and its outskirts.
Black-And-Blue Sea
According to Noskovets, the most affected area is Sochi’s Lazarevsky district, where tourist Aida Kobzh recently spotted the dead dolphins.
“The biggest hazard is posed by a river that runs through the Lazarevsky district, an area with a high concentration of sanatoriums, including for children,” says Noskovets. “The infamous Olympic dump lies nearby, and it has no waste-treatment system. This small mountain stream, which used to have fish, is now cloudy, brown and foamy. It collects waste and carries it to beaches that once counted among the most beautiful in the area.”
Noskovets says the dolphin die-off should act as a wake-up call. She says the authorities must urgently sound the alarm and warn visitors about the health hazards of bathing on certain Black Sea beaches before the tourist season reaches its peak.
“If sea creatures that are adapted to life in the sea react this way, what will the consequences be for humans?” Noskovets says. “Every year, numerous people suffer poisoning incidents after bathing in the sea, and these are always blamed on food poisoning. It is a nasty lie from our authorities, who are afraid of telling the truth — that the Black Sea is simply being poisoned.”
David DeKok, author of “Fire Underground,” a book about the town, poses Thursday on abandoned Route 61 in Centralia, Columbia County.
By Michael Rubinkam / The Associated Press
CENTRALIA, Pa. — It’s an anniversary the few remaining souls who live here won’t be celebrating.
Fifty years ago on Sunday, a fire at the town dump ignited an exposed coal seam and still burns today. It set off a chain of events that eventually led to the demolition of nearly every building in Centralia — a whole community of 1,400 simply gone.
All these decades later, the Centralia fire maintains its grip on the popular imagination, drawing visitors from around the world who come to gawk at twisted, buckled Route 61, at the sulfurous steam rising intermittently from ground that’s warm to the touch, at the empty, lonely streets where nature has reclaimed what coal-industry money once built. It’s a macabre story that has long provided fodder for books, movies and plays — the latest one debuting in March at a theater in New York.
Yet to the handful of residents who still occupy Centralia, who keep their houses tidy and their lawns mowed, this borough in the mountains of northeastern Pennsylvania is no sideshow attraction. It’s home, and they’d like to keep it that way.
“That’s all anybody wanted from day one,” said Tom Hynoski, who’s among the plaintiffs in a federal civil rights lawsuit aimed at blocking the state of Pennsylvania from evicting them.
Centralia was already a coal-mining town in decline when the fire department set the town’s landfill ablaze on May 27, 1962, in an ill-fated attempt to tidy up for Memorial Day. The fire wound up igniting the coal outcropping and, over the years, spread to the vast network of mines beneath homes and businesses, threatening residents with poisonous gases and dangerous sinkholes.
After a contentious battle over the future of the town, the side that wanted to evacuate won out. By the end of the 1980s, more than 1,000 people had moved and 500 structures were demolished under a $42 million federal relocation program.
But some holdouts refused to go — even after their houses were seized through eminent domain in the early 1990s. They said the fire posed little danger to their part of town, accused government officials and mining companies of a plot to grab the rights to billions of dollars’ worth of anthracite coal, and vowed to stay put.
After years of letting them be, state officials decided a few years ago to take possession of the homes. The state Department of Community and Economic Development said Friday it’s in negotiations with one of the five remaining homeowners; the others are continuing to resist, pleading their case in federal court.
Residents say the state has better things to spend its money on. A handwritten sign along the road blasts Gov. Tom Corbett, the latest chief executive to inherit a mess that goes back decades.
“You and your staff are making budget cuts everywhere,” the sign says. “How can you allow [the state] to waste money trying to force these residents out of their homes? These people want to pay their taxes and be left alone and live where they choose!”
Whether it’s safe to live there is subject to debate.
Tim Altares, a geologist with the Pennsylvania Department of Environmental Protection, said that while temperatures in monitoring boreholes are down — possibly indicating the fire has followed the coal seam deeper underground — the blaze still poses a threat because it has the potential to open up new paths for deadly gases to reach the remaining homes.
“It’s very difficult to quantify the threat, but the major threat would be infiltration of the fire gases into the confined space of a residential living area. That was true from the very beginning and will remain true even after the fire moves out of the area,” Mr. Alteres said.
Nonsense, say residents who point out they’ve lived for decades without incident.
Carl Womer, 88, whose late wife, Helen, was the leader of a faction that fiercely resisted the government buyout, disagrees the fire poses any threat.
“What mine fire?” Mr. Womer asked dismissively as he hosed down his front porch, preparing, he said, for a Memorial Day picnic. “If you go up and see a fire, you come back and tell me.”
Author and journalist David DeKok, who has been writing about Centralia for more than 30 years, said that while he believes Mr. Womer’s house is too close to the fire to safely live there, Mr. Hynoski and his neighbors are far enough away.
“I don’t think there’s any great public safety problem in letting those people stay there,” said Mr. DeKok, author of “Fire Underground,” a book on the town.
Many former residents, meanwhile, prefer to talk about the good times, their nostalgia taking on a decidedly golden hue.
“I loved it. I always liked Centralia from the time I was old enough to understand what it was,” said Mary Chapman, 72, who left in 1986 but returns once a month to the social club at the Centralia fire company.
“If you came out of your house and you couldn’t get your car started, the neighbor would come out and he’d help you. You didn’t even have to ask,” Ms. Chapman continued. “Of course the neighbors knew your business, but they also were there to help you, too.”

Earthquake hits Southern Lebanon
Residents of the Lebanese southern city of Tyre and its suburbs at around 10:47 a.m. on Wednesday felt the ground shake, the National News Agency reported.
A small quake measuring 3.6 on the Richter scale jolted cities in southern Lebanon on Wednesday, without causing any injuries or damage, the Bhannes Center for Seismic and Scientific Research announced, adding “There is nothing to worry about.”
Residents of the southern city of Tyre and its suburbs felt the earthquake at around 10:47 am, the National News Agency said.
Residents also felt the tremor in Nabatiyeh, the agency added.
Antananarivo- At least 72 people were killed when the tropical storm Irina hit northern Madagascar in late February, causing floods and landslides, authorities said on Thursday.
Three people were also reported missing and some 77,911 displaced, said the National Office for Disaster and Risk Management, BNGRC.
Russia Volcano Bezymianny put on Code Red for imminent eruption
(TheWeatherSpace.com) – One of the most active volcanoes in the world has been put on aviation color code red, the highest alert given by the Kamchatka Volcanic Eruption Response Team.
KVERT assigned the code on Tuesday and warns of an imminent eruption. “Activity of the volcano continuously increases,” says the alert. “Strong ash explosions up to 42,640 ft (13 km) a.s.l. possible at any time. Ongoing activity could affect international and low-flying aircraft.
Sakurajima volcano (Kyushu, Japan) activity update: increased numer and size of ash eruptions, reaching 1.2-3 km height above crater
Sakurajima volcano appears to be at higher levels of activity, as the last week has seen an increased average number and size of eruptions. According to the latest USGS / Smithsonian report “explosions during the past week “often” produced plumes that rose to altitudes of 1.2-3 km (4,000-10,000 ft) a.s.l. and drifted NW, E, and SE.” Many obseervations of ash plumes originate of analysis of satellite data and dedicated Volcanic Ash Advisory Centers (VAAC) around the world monitor them and transmit real-time information about hazardous ash plumes to aircraft and air traffic control centers. Such reports are often complemented by direct observations from pilots passing nearby.
Blast shakes restless volcano in remote Aleutian Islands

Cleveland Volcano, 940 miles southwest of Anchorage, probably burped up a small amount of ash — a potential hazard to trans-oceanic air travel — but the ash did not appear to reach above 20,000 feet, said Steve McNutt, a researcher with the Alaska Volcano Observatory.
Double Blast – Exciting Space Weather from AR11429

http://www.thesuntoday.org – Sunspot group, AR11429 (Active Region), is at it again. When it first began its journey across the Earthward side of the Sun it released an M-class flare, an X-class flare and several more M flares, along with several CMEs. Early on March 7, 2012 (00:24 UT) it erupted with an X5.4 flare, a coronal wave and a CME. Shortly after that (01:14) it erupted again with an X1.3 flare, another coronal wave and a CME. The CMEs were observed by the Cor2 coronagraph on STEREO Behind. Solar radio bursts also accompanied the flares and proton flux began to rise. This proton event is probably due to both the flares and the CME produced shocks. Earth’s magnetosphere is already disturbed due an early CME from AR11429 and it will probably feel at least a glancing blow from one or both of the recent CMEs in the next few days. We await more data and predictions from the various spacecraft and space weather research teams. More is sure to come from AR11429.

Magnetic Field
Earth’s magnetic field is being shaken like a snow globe by the large solar storm. After hurtling through space for a day and a half, a massive cloud of charged particles arrived Tuesday and could disrupt utility grids, airline flights, satellite networks and GPS services, especially in northern areas. But the same blast also could paint colourful auroras farther from the poles than normal. Scientists say the storm, which started with a massive solar flare early in the week, is growing as it races outward from the sun, expanding like a giant soap bubble and moving at 6.4 million km/h. “It’s hitting us right in the nose.”
The storm is part of the sun’s normal 11-year cycle, which is supposed to reach peak storminess next year. Solar storms do not harm people, but they do disrupt technology. And during the last peak around 2002, experts learned that GPS was vulnerable to solar outbursts. Because new technology has flourished since then, scientists could discover that some new systems also are at risk.
A decade ago, this type of solar storm happened a couple of times a year. “This is a good-size event, but not the extreme type.” The region of the sun that erupted can still send more blasts earth’s way. Another set of active sunspots is ready to aim at Earth right after this. “This is a big sun spot group, particularly nasty. Things are really twisted up and mixed up. It keeps flaring.”
Storms like this start with sun spots. Then comes an initial solar flare of subatomic particles that resemble a filament coming out of the sun. That part already hit earth only minutes after the initial burst, bringing radio and radiation disturbances. After that comes the coronal mass ejection, which looks like a growing bubble and takes a couple of days to reach earth. It’s that ejection that could cause magnetic disruptions today. “It could give us a bit of a jolt.” The storm follows an earlier, weaker solar eruption that happened Sunday. Still, the potential for problems is widespread. Solar storms have three ways they can disrupt technology on earth: with magnetic, radio and radiation emissions. This is an UNUSUAL situation, when all three types of solar storm disruptions are likely to be strong. That makes it the strongest overall since December 2006.
That means “a whole host of things” could follow.
Solar storms also can make global positioning systems less accurate and cause GPS outages. The storm could trigger communication problems and additional radiation around the north and south poles – a risk that probably will force airlines to reroute flights. Some already have done so. Satellites could be affected, too. NASA is not taking any extra precautions to protect astronauts on the International Space Station from added radiation. The charged particles are expected to hit Earth at 4,000,000 mph (6,400,000 km/h), and NOAA predicts the storm will last until Friday morning.
