Dear Collaborators,

Solar activity continues at a moderate level. The largest event since the last message was an M1.0 flare at 12:49 UT today from an unnumbered region (S10E23), which emerged a bipolar sunspot group. This M1.0 flare was superimposed on the gradual phase of a long-duration C5.6 flare at 07:46 UT produced by a region currently beyond the South East limb (N14E88). The eastern part of the target region has been renumbered as NOAA 13842 and has been confirmed as a beta-gamma/D-type sunspot group, with an area of 220 MSH. Today the default target region will remain with NOAA 13842 due to its overall size and prior flaring history. Further C-class activities are expected, with a chance of another low-M flare in the next 24 hours.

The position of NOAA 13842 on 29-Sep-2024 at 11:30 UT is:

S14E50 (-713", -301")
