vichyschwa writes "A Coronal Mass Ejection resulting from an X3 Solar Flare earlier today is forcing the ISS and Shuttle astronauts to take cover and may result in communication disruptions. Last week, the same sunspot generated what astronomers described as a rarely imaged solar tsunami. The activity began with an X9 flare Dec. 5. According to Spaceweather.com, "satellites may experience some glitches and reboots, but astronauts are in no danger." However, the astronauts were ordered to a protective area of the space station as a precaution."
