Small active region NOAA 2790 produced a long duration C7 flare and was associated with an earth-directed full halo coronal mass ejection. UPDATE: As predicted, the CME arrived at Earth early on 10 December but it did not produce significant geomagnetic activity.

Two active regions are rotating over the southeast solar limb, and the second group contains a really big sunspot.

On 11 November, a fairly simple sunspot region produced a long duration C-class flare. This was already the third sunspot region observed in November, and an indication that the new solar cycle 25 (SC25) is quickly gaining in strength.

NOAA 2781 has become the largest sunspot group so far this solar cycle. It produced numerous C-class flares and drove the solar radio flux to its highest levels this year.

Last week, solar observers were treated on no less than 2 relatively complex sunspot regions. Each group produced a number of C-class flares before starting a gradual decay.

A relatively large and complex prominence eruption took place at the Sun's northeast limb on 23 October. The associated CME does not seem to have an earth-directed component.
