Analysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: 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 (26 Nov, 27 Nov, 28 Nov). IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field has been at unsettled to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 874 km/s at 25/1054Z. Total IMF reached 9 nT at 24/2100Z. The maximum southward component of Bz reached -7 nT at 25/0811Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 3722 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at active to minor storm levels on days one and two (26 Nov, 27 Nov) and active levels on day three (28 Nov). III.
