Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 62 Issued at 2200Z on 03 Mar 2022

IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 02/2324Z from Region 2960 (S21E81). There are currently 7 numbered sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (04 Mar, 05 Mar, 06 Mar).

IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 440 km/s at 02/2100Z. Total IMF reached 8 nT at 03/1909Z. The maximum southward component of Bz reached -5 nT at 03/1941Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 417 pfu.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (04 Mar) and quiet to active levels on days two and three (05 Mar, 06 Mar).
