3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 585 km/s at 22/2028Z. Total IMF reached 19 nT at 21/2322Z. The maximum southward component of Bz reached -11 nT at 21/2102Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 207 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on days one and two (23 Dec, 24 Dec) and quiet to active levels on day three (25 Dec).
Solar ActivityAnalysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (23 Dec, 24 Dec, 25 Dec).
