SDF Number 60 Issued at 2200Z on 01 Mar 2022

IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 01/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (02 Mar, 03 Mar, 04 Mar).

IIA. Geophysical Activity Summary 28/2100Z to 01/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 557 km/s at 01/1506Z. Total IMF reached 6 nT at 28/2136Z. The maximum southward component of Bz reached -5 nT at 28/2313Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 216 pfu.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (02 Mar, 04 Mar) and quiet levels on day two (03 Mar).
