Analysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 6 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (22 Nov, 23 Nov, 24 Nov). IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 489 km/s at 21/0407Z. Total IMF reached 14 nT at 20/2127Z. The maximum southward component of Bz reached -9 nT at 20/2248Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 547 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (22 Nov) and quiet levels on days two and three (23 Nov, 24 Nov). III.
