10th September

Solar activity returned to low levels. Region 2157 (S14W05,
Ekc/beta-gamma-delta) produced the majority of the flare activity,
including the largest flare of the period, a C3/1n flare at 09/1226 UTC,
and a C2/Sf flare at 10/0524 UTC. This region maintained its delta
magnetic configuration and continued to exhibit signs of growth, mainly
in its intermediate spots. Region 2158 (N15E07, Dkc/beta-gamma) had
noticeable separation of the penumbral area, separating into two
separate magnetic polarities, thus losing its delta magnetic
configuration. Regions 2157 and 2158 continue to be the areas of
interest as they are still the largest and most magnetically complex
regions on the visible disk.
