Analysis of Solar Active Regions and Activity from 19/2100Z to 20/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 4 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 (21 Nov, 22 Nov, 23 Nov). IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 456 km/s at 20/1651Z. Total IMF reached 17 nT at 20/1417Z. The maximum southward component of Bz reached -10 nT at 20/1937Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2883 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (21 Nov), quiet to unsettled levels on day two (22 Nov) and quiet levels on day three (23 Nov).
