LOTS OF SOLAR FLARES: During the past 48 hours, monster sunspot AR2192 has unleashed seven M-class solar flares. The most powerful of the bunch (Oct 22nd at 0159 UT) was an M9-class eruption that almost crossed the threshold into X-territory. NASAs Solar Dynamics Observatory recorded the extreme ultraviolet flash: UV radiation from the flare ionized Earths upper atmosphere, causing a brief blackout of HF radio communications on the dayside of Earth (e.g., parts of Asia and Australia). In addition, the explosion might have hurled a CME into space. Confirmation awaits the arrival of coronagraph data from the Solar and Heliospheric Observatory (SOHO).
