3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical 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).
Solar ActivityAnalysis 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).
