Details:
Many sunspots these days. It may be the moment of maximum in the 11-year cycle, but we have to wait months to get a smoothed graph in order to recognize the real maxima. The pictures show the unusual crescent-shaped string/group of Active Regions (which are in turn Sunspot groups) which dominates the disc since a week. As indicated in picture, most (three) of these regions have a delta classification (X flare possible): Basically this group is a single giant delta region. This means that an X flare from this group is likely one of next days. One of these regions, 3876, is here caught producing a moderate flare (in white).
The big filament (prominence) at bottom right is (as seen in SDO images) connected to this group and unstable since one week: vibrating, sometimes partly flaring, sometimes partly exploding. An entire explosion of this filament would generate a very interesting CME. A similar filament, southward of this, exploded entirely on day 29th giving quite a show.
The N hemisphere is (since Spring) more lazy than the S. But it now features two gamma regions (medium flares possible) and the medium-big sunspot 3879, which is most likely the return of big sunspot 3848 (the responsible for the big aurora of October 10-11).
