As we previously mentioned on WUWT, the Sunspot 2192 which is as large as Jupiter had the potential of hurling large solar flares toward Earth. According to NASA’s spaceweather.com “Giant sunspot AR2192 has a ‘beta-gamma-delta’ magnetic field that harbors energy for strong explosions. NOAA forecasters estimate an 85% chance of M-class flares and a 45% chance of X-flares on Oct. 24th. If an explosion does occur, it will be geoeffective because the sunspot is directly facing Earth.”
It has just released what appears to be an x-class flare, possibly an X3.
