Dear Collaborators,

Solar activity is at a moderate-to-low level. The largest event since the last message was a C9.1 flare at 03:23 UT today (11/22), produced by the target region 13901 (S07E14). It remains classified as a beta-gamma /D-type sunspot group and produced another two C-class flares in the period. However, its spot activity appears relatively stable. Please note that a limb region NOAA 13905 (S09E71, beta/D-type) also produced two mid-C-class flares in the period and now exhibits relatively high current helicity. Today, the target region shall switch to NOAA 13905. Further C-class activity is expected, with a chance of low M-class flares in the next 24 hours.

The position of NOAA 13905 on 22-Nov-2024 at 12:30 UT is:

S09E71 (-908",-162")
