Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 7 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 (25 Nov, 26 Nov, 27 Nov). IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field has been at unsettled to active levels for the past 24 hours. Solar wind speed reached a peak of 756 km/s at 24/1721Z. Total IMF reached 15 nT at 24/1039Z. The maximum southward component of Bz reached -11 nT at 24/1107Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 344 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (25 Nov), unsettled to minor storm levels on day two (26 Nov) and active levels on day three (27 Nov).
