solar flare alert!
The crew was directed into 'storm shelter' areas on board the station
overnight to seek highest radiation protection, due to a massive new solar flare. |

According to http://spaceweather.com/ Sunspot 930 has just unleashed another big solar flare, an X3-class explosion at 0240 UT on Dec. 13th... As a result of the blast, a radiation storm is underway. Based on the energy and number of solar protons streaming past Earth, NOAA ranks the storm as category S2: satellites may experience some glitches and reboots, but astronauts are in no danger. The explosion probably hurled a coronal mass ejection toward Earth. (Confirmation from SOHO is still pending.) Sky watchers should be alert for auroras when it arrives on Dec. 14th or 15th. |

Right. But last night's concern wasn't the charged particals
but the speed-of-light nasties. "George" wrote in message ... "Jim Oberg" wrote in message ...

The radiation that they worry about is charged particles, just much more energetic than the typical particles in the solar wind or a CME. The energetic charged particles arrive soon after the x-ray burst, but don't travel at quite the speed of light. Paul |

The problem is that by the time you note the x rays, its all rather too
late. As you say though, you can avoid the slower charged particles. Anyone find it odd that at this so called low time in the cycle, we should have this active area? Also, why does it spew its junk our way, or is it in fact doing it all the time and we only notice when its pointed our way!
