CHANCE OF FLARES TODAY: NOAA forecasters say there is a 75% chance of M-class solar flares today, April 19th, and a 25% chance of powerful X-flares. The most likely source would be sunspot complex AR2993-94, which is crackling with flares as it turns toward Earth.
Very impressive show today in AR 2993 and 2994 ! A ?-shaped flare at 8h06 UT with a big eruptive prominence nearby, Ellerman bombs at 9h25 UT and a new, stronger, flare at 10h30 UT in the same location as the previous one. AiryLab Celestron 8 solar telescope, DayStar Quantum H alpha filter (tuned to Ha + 0.8 A for Ellerman bombs). Poor to average seeing. Taken by Francois Rouviere on April 18.
