Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: 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 (24 Nov, 25 Nov, 26 Nov). IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 499 km/s at 23/1644Z. Total IMF reached 13 nT at 23/1833Z. The maximum southward component of Bz reached -8 nT at 23/1157Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 596 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (24 Nov), quiet to minor storm levels on day two (25 Nov) and unsettled to minor storm levels on day three (26 Nov).
