Dear Collaborators,

Solar activity continues at a high level. The Major Flare Watch region NOAA 13615 produced an M7.4 flare at 07:23 UT today plus an M2.1 flare at 23:17 UT yesterday. It also produced five C-class flares. This region retains a beta-gamma/E-type configuration but increases in both the sunspot area and number of spots. Further low M-class flares are expected with a chance of an additional major flare (>M5) in the next 24-48 hours.

The position of NOAA 13615 on March 20 at 08:30 UT is:

S12E43 (-644", -114")
