Strong (R3) Flare Activity Observed - 05 May 2024
published: Monday, May 06, 2024 16:35 UTC

Region 3663 produced X1 flares (R3/Strong) at 0601 UTC and 1154 UTC on 05 May, in addition to multiple M-class flares (R1-R2/Minor-Moderate) over the past 24 hours. Region 3663 is the largest and most complex sunspot region on the disk, and has produced a total of fourteen M-flares and three X-flares since it emerged on 30 Apr. M-class flare activity is expected, with a chance for additional X-class flares, through 08 May due to the flare potential and history of Region 3663.
