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.

eruption and more information about this increasingly active sunspot.
