Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 61 Issued at 2200Z on 02 Mar 2022

IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M2 event observed at 02/1739Z from Region 2958 (N20E24). There are currently 5 numbered sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (03 Mar, 04 Mar, 05 Mar).

IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 525 km/s at 01/2210Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 190 pfu.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (03 Mar), quiet to unsettled levels on day two (04 Mar) and quiet to active levels on day three (05 Mar).
