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.

So far none of the eruptions has been squarely Earth-directed, but this could change in the days ahead as the sun's rotation turns the active region toward our planet.
Now might be a good time to sign up for space weather alerts.
