Dear Collaborators,
Solar activity continues at a very low level since the last message, with the GOES soft X-ray flux flat at ~C1 in general. Yesterday's target region NOAA 13254 (S25W48, beta/C-type) and the neighbouring NOAA 13250 (S19W42, alpha/A-type) only produced two B8 flares and have shown signs of decay during the period. Two C1-class flares occurred in a spotless region (N23W21) located in the northwest to NOAA 13252 (N13W14, alpha/A-type). Please note that there were two high B-class flares from behind the southeast limb in the period and the dynamic loops are visible in EUV images. The target shall switch to this currently unnumbered region at the southeast limb. C-class flares are expected over the next 24 hours.
The approximate position of the target on 16-Mar-2023 at 08:30 UT is:
S20E87 (-900", -350")
