R2 (Moderate) activity from Region 2192
published: Wednesday, October 22, 2014 15:50 UTC

Region 2192 produced its 7th M-class (R1/R2-Minor-Moderate) flare in the past 48 hours.  The M8 (R2-Moderate) flare occurred on October 21st at 9:59 EDT (22/0159 UTC) and is the largest flare to occur since the X1 flare from the same region on October 19th. Region 2192 remains a very large spot group with a fairly complex magnetic structure and will continue to be the area of interest for the next several days.  Stay tuned for updates.
