SDF Number 60 Issued at 2200Z on 01 Mar 2021

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 0 numbered sunspot regions on the disk.

IB. Solar Activity Forecast

Solar activity is expected to be very low 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 major storm levels for the past 24 hours. Solar wind speed reached a peak of 538 km/s at 01/0902Z. Total IMF reached 14 nT at 01/0328Z. The maximum southward component of Bz reached -13 nT at 01/0307Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1074 pfu.

IIB. Geophysical Activity Forecast

The geomagnetic field is expected to be at quiet to minor storm levels on day one (02 Mar), quiet to active levels on day two (03 Mar) and quiet to unsettled levels on day three (04 Mar).
