Dear Collaborators,

Solar activity reached a high level in the past 24 hours. The largest
event since the last message was an X1.1 flare at 15:40 UT today
from NOAA 13217. 13217 was the most productive and also produced
5 low M-class flares. This region emerged new sunspots and has
been classified as a beta-gamma-delta/E-type configuration. Today
the Major Flare Watch region shall switch to NOAA 13217. In addition,
NOAA 13220 (S14E46, alpha/H-type) and NOAA 13222 (N29W84,
beta/D-type) also produced several low M-class flares. Further low
M-class flares are expected with a good chance for additional >=M5
flare in the next 24-48 hours.

The position of NOAA 13217 on 12-Feb-2023 08:30 UT

S09E31 (-496", -55")
