The largest and most interesting active region of the current solar cycle - Region 2192 ('beta-gamma-delta") - erupted on October 26, 2014 with its fifth X-class solar flare since it rotated into Earth view. The event started at 10:04, peaked at 10:56 as X2.0 and ended at 11:18 UTC. Like the previous major eruptions from this region this was a long duration event which again failed to deliver a significant CME.
The eruption produced an R3 (Strong) radio blackout - area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point. Wide area blackout of HF (high frequency) radio communication for about an hour. There are about 175 such events on average during one solar cycle...
