Dear Collaborators,

Solar activity has been at a low level since the last message, with the largest event being a C8.7 flare at 11:25 UT yesterday produced by the target region NOAA 13615. 13615 also produced another five C-class flares during the period. It remains a beta-gamma-delta/ E-type configuration. Today we continue the Major Flare Watch on this region due to its growing current helicity. Please note that another region, NOAA 13614 (N17E11), also produced five C-class flares including a C8.4 at 13:45 UT today, which has a beta/D-type sunspot group. Further C-class activities are expected, with a chance of an isolated flare above M5 in the next few days.

The position of NOAA 13615 on March 22 at 16:30 UT is:

S12E15 (-244", -88")
