Dear Collaborators,

Solar activity has been at moderate levels for the past 24
hours. The largest event since the last message was an
M3.1 flare at 02:45 UT today produced by a newly numbered
region NOAA 13217. 13217 is rotating onto the visible disk
and has been classified as a beta/D-type configuration. This
region also produced two another low M-class flares (M1.5
and M1.1). It shows a high and increasing current helicity.
Today the Major Flare Watch region will switch to NOAA 13217.
But if possible, please also include the southeast limb region
(S12E85) in your field of view, which produced an M2.9 at 08:49 UT
today. Yesterday’s target region NOAA 13213 (beta-delta/E-type)
produced 3 M1 flares in the period, with emerging new sunspots
and new magnetic fluxes. Additional low M-class flares are expected
from various regions with a chance of an above M5 flare in the next
24-48 hours.

The position of NOAA 13217 on 9-Feb-2023 12:30 UT

S07E65 (-876", -71")
