Bright X-ray Solar Flare

Source - Space Weather News for Nov. 6, 2010:

BRIGHT SOLAR FLARE: Active sunspot 1121 has just unleashed one of the brightest x-ray solar flares in several years, an M5.4-class eruption at 15:36 UT on Nov. 6th. Radiation from the flare created a wave of ionization in Earth's upper atmosphere that altered the propagation of low-frequency radio waves. There was, however, no bright CME (plasma cloud) hurled in our direction, so the event is unlikely to produce auroras in the nights ahead. Visit for a movie of the eruption and more information about this increasingly active sunspot.
