Dear Collaborators,
Solar activity continues at a very low level. The largest event in the past 24 hours was a C1.6 flare at 04/11/04:59 UT emergent from a plage region (S14E06, just in the north of NOAA 12987). Now there are two regions with sunspots on the visible disk, NOAA 12983 and 12988, the latter of which is a newly emerged region having a beta/B-type configuration. The target NOAA 12983 has decayed to an alpha/A-type region and produced four B-class flares during the period. We will watch this region for a further 24 hours until it rotates over the west limb. B-class activities are expected and some C-class flares are probable in the next 24 hours.
The position of NOAA 12983 on April 12 at 03:30 UT is:
N20W85 (895", 333")
