Dear Collaborators,

Solar activity has been at a low level since the last message. Yesterday's target region NOAA 13256 (S23E12, beta/C-type) was quiescent during the period. The largest event was an impulsive C4.6 flare at 03/21/13:46 UT from NOAA 13257 (S28E33, alpha/H-type) which also produced another three low C-class flares in the period. Today the target shall switch to this region. The nearby region NOAA 13259 (S23E24, beta/B-type) also produced two C1 flares during the period. If possible, please also include NOAA 13259 and 13256 in your field of view. Further C-level flares are expected in the following 24 hours, with a slight chance for a low M-class flare.

The position of NOAA 13257 on 22-Mar-2023 at 12:30 UT is:

S28E33 (-464",-363")
