Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 03/1741Z. There are currently 4 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 (04 Dec, 05 Dec, 06 Dec). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 656 km/s at 02/2114Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 17351 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (04 Dec) and quiet levels on days two and three (05 Dec, 06 Dec). III.
