Solar activity has been moderate. The NOAA/SXI test imagery observed an M2 event from Region 9714 at 02/2206 UTC as it rotated around the southwest limb of the sun. Region 9715 (N04W49) continues to show a slight decay from yesterday. New Region 9727 (S22E68) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low to moderate. Isolated major flares are possible from Regions 9715 and 9718 (S07E03).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled. Isolated active conditions are possible for 04 - 05 December due to coronal hole effects.
