Dear Collaborators,
Yesterday's target NOAA 12983 was the source of seven C-class flares (the largest one being a C3.8 at 04/12/06:38 UT) and also a few B-class events in the past 24 hours. 12983 has rotated beyond the west limb. Today the target will switch to a newly numbered region NOAA 12989. This region has an alpha/A-type configuration but has produced a B-class flare. It seems to be emerging new magnetic fluxes in its leading portion. B-class activities are expected with a chance of some low C-class events in the following 24 hours.
The position of NOAA 12989 on April 13 at 03:30 UT is:
N19E71 (-856", 339")
