Bright X-ray 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 November 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.
