Dear Collaborators,
Solar activity has reached intermediate levels since the last message. The largest event was a C6.0 flare at 13:59 UT on 09-Dec-2022 produced by an unnumbered limb region (S17E89). This region has produced more than ten C-class flares. Today the target shall switch to this limb region. Yesterday's target NOAA 13153 (S17W30) only produced a C1.4 flare and a B8.9 flare though it was classified as a beta-gamma/F-type configuration. Additional C-class activities are expected with a chance of a low M-class flare in the next few days.
The approximate position of the target on 9-Dec-2022 16:30 UT
S19E89 (-900", -325"):
