Dear Collaborators,
The Major Flare Watch region NOAA 12975 produced an M9.6 flare at 03/31/18:17 UT plus three low C-class flares in the past 24 hours. Another two regions, NOAA 12981 (S26E27, beta/D-type) and 12978 (S18E24, beta-gamma/E-type) also produced numerous C-class flares. We will continue the Major Flare Watch on NOAA 12975 today. It retains a beta-gamma-delta/D-type configuration when rotating to the west limb. Another major flare is still likely in the following two days.
The position of NOAA 12975 on April 1 at 07:30 UT is:
N13W56 (777", 274")
