Solar Flare: Puissant M.9 ce matin!!!

SOLAR FLARE! Solar activity is high. On October 24th at 00:30 UT, Earth-facing sunspot AR1877 erupted, producing a powerful M9-class solar flare. NASA's Solar Dynamics Observatory recorded the blast:

A flash of extreme UV radiation from the flare ionized Earth's upper atmosphere and created a brief HF radio blackout on the sunlit (Pacific) side of the planet. The blackout has since subsided. A CME might be en route to Earth, but we're still waiting on SOHO coronagraph data to confirm this possibility.

Meanwhile, more flares are in the offing. Two large sunspots, AR1875 and AR1877, have 'beta-gamma-delta' magnetic fields that harbor energy for strong eruptions. NOAA forecasters estimate a 40% chance of M-flares and a 5% chance of X-flares during the next 24 hours.
