Dear Collaborators,
Solar activity continues at moderate levels in the past 24 hours. The largest event since the last message was an M2.2 flare at 07:59 UT today produced by a newly emerged region NOAA 13208 (N09W71, beta/C-type). 13208 also produced three C-class flares. The target region NOAA 13213 increased in sunspot area and number of spots and has been classified as a beta-gamma/F-type configuration. This region produced three M1 (M1.2, M1.7, M1.6) flares in the period. Today the Major Flare Watch region shall remain NOAA 13213 for one more day. Please note that some other regions (NOAA 13220, 13222) also produced several M1 flares. Further low M-class flares are expected still with a chance of an above M5 flare in the next 24-48 hours.
The position of NOAA 13213 on 11-Feb-2023 08:30 UT
N30W44 (586", 553")
