NASA has issued a communication about the event that plays down the importance of what is happening. Apart from an Item in Astronomy and Space News, the story was picked up - as far as I can tell - so far only by a paper in Brisbane, Australia. Solar_Flare.jpg A major solar flare not seen in 30 years But a more detailed account comes from Russia. The paper Commersant puts the event in perspective saying that the flare was classified an X-9, meaning an extremely powerful event. Except for its timing which directed the energy away from earth, the flare could have disruptive effects on both electronic communications and health. But we seem to be too preoccupied with the politics of man-made global warming to pay much heed to energetic phenomena that easily dwarf anything our technology could bring to bear. Or are we being purposely being kept in the dark? Who would have thought that Russian scientists and press are more apt to discuss events likely to influence our lives than the media in the west? Times indeed seem to be a'changing... The largest electromagnetic energy emission in the last 30 years has been recorded on the Sun, the Shternberg State Astronomy Institute said on Thursday. This energy outburst may damage equipment of space satellites, the scientists say. Doctors warn that the emission is dangerous for those afflicted with cardiovascular illnesses as well as for healthy people. Scientists at the Shternberg Astronomy Institute of the Moscow State University have reported record-high emissions of electromagnetic energy on the Sun, the biggest since the 1970s. Over the past few days, the volume of sun radiation, or X9, has exceeded the normal level 1,000-fold. The scientists call this phenomenon an anomaly and say that the Sun is now in a stage when sunspots, sources of high electromagnetic radiation, are unusual. “Outbursts on the Sun like this have been extremely infrequent over the past 30 years,” said Igor Nikulin of the Shternberg Institute. “What is more, we have never had a chance to observe such emissions with the sun at its minimal activity.” Here, for archive purposes, the reports: - - - This is the NASA release as quoted in Astronomy & Space News: Sun unleashes major solar flare The Sun is just past its low-point in an 11-year cycle of activity. But big eruptions can happen anytime. One just did. A major X-9 flare erupted last week. It emanated from a large sunspot, numbered 929, which is just coming into view around the eastern limb of the Sun. The flare lifted off the Sun and was directed away from Earth. But this sunspot will rotate toward the centre of the Sun over the next few days and could offer up more major blasts that could take direct aim at our planet, forecasters say. It may cause auroras in Tasmania later this week. Flares of this magnitude (X-class flares are all major) can damage satellites and disrupt telecommunications on Earth. They can also threaten astronauts in space. NASA sometimes orders astronauts aboard the International Space Station to retreat to the most well protected part of the orbiting outpost to avoid excess radiation exposure. Spacewalks are avoided during solar storms. Sunspots are dark regions of the Sun where intense magnetic activity caps the upwelling of material from below. Sometimes a cap blows, and a visible flare results. The flares are loaded with X-rays and other radiation, all of which reaches Earth moments after the eruption and can be accompanied by a shower of protons. These storms can arrive in moments with little warning and can be deadly. Many flares are accompanied by clouds of electrified gas called coronal mass ejections, which can slam Earth a day or so later. Earth is somewhat shielded from solar storms, but some of the radiation leaks through our protective magnetic field. Experts say space radiation is one of the biggest threats to current and future space missions, including the effort to establish a lunar base. NASA. - - - Kommersant in Russia has this report dated 8 December 2006: Powerful Magnetic Storm Approaches the Earth The largest electromagnetic energy emission in the last 30 years has been recorded on the Sun, the Shternberg State Astronomy Institute said on Thursday. This energy outburst may damage equipment of space satellites, the scientists say. Doctors warn that the emission is dangerous for those afflicted with cardiovascular illnesses as well as for healthy people. Scientists at the Shternberg Astronomy Institute of the Moscow State University have reported record-high emissions of electromagnetic energy on the Sun, the biggest since the 1970s. Over the past few days, the volume of sun radiation, or X9, has exceeded the normal level 1,000-fold.

First, the scientists observed flashes on the Sun which were classified as moderate. However, the flashes were followed on Tuesday by massive outbursts of electromagnetic energy. “Such a large cloud of hot plasma has been released into space that even electronic equipment on space satellites may be damaged,” Vladimir Matveev at the Moscow Aviation Institute says. The Sun’s electromagnetic anomaly has not reached the Earth yet. However, the Earth is expected to reach the sunspots quite soon. The encounter may happen this weekend, scientists at the Shternberg Astronomy Institute report. Igor Nikulin says: “If the area of the sunspots does not diminish in three or four days and the emissions continue, it may have a serious influence on the magnetic field of the Earth.” A cloud of hot plasma from the sunspots will make the Earth’s magnetic field vibrate and will cause a powerful magnetic storm.” Doctors recommend their patients to keep to a special regime during the magnetic storm. People with cardiovascular illness are believed to be at a particular risk. However, quite healthy people should be on their guard as well. “One should not go overboard with drinking, going to the sauna or doing extra work,” Vladimir Ryabinin, chief physician at the Sklifosovskiy Ambulance Institute, advises. Other doctors suggest that people pay close attention to their health conditions during the days of the magnetic storm and go to consult their doctors in case of any problem.

easy on the sauna and drinking binges
"The illegal we do immediately. The unconstitutional takes a little longer." Easy for you to say ;)
Maybe we'll be looking for some more astronauts - to fly the shuttle back.
We had two blackouts yesterday spanning a couple different electricity providers. Unexplained.

Astronauts venture outside for space station work Reuters HOUSTON - Two spacewalking astronauts added a new piece to the metal backbone of the International Space Station on Tuesday, clearing the way for a critical power rewiring later this week.
