Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C6 event observed at 02/1555Z from Region 2222 (S19W10). There are currently 9 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (03 Dec, 04 Dec, 05 Dec). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 648 km/s at 02/0259Z. Total IMF reached 10 nT at 01/2144Z. The maximum southward component of Bz reached -10 nT at 01/2144Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (03 Dec, 04 Dec, 05 Dec). III.
