Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 62 Issued at 2200Z on 03 Mar 2021IA. 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
03/0003Z from Region 2807 (S18E29). There are currently 2 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast

field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 692 km/s at 03/0350Z. Total IMF
reached 7 nT at 02/2227Z. The maximum southward component of Bz reached
-6 nT at 03/0011Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 4797 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on days one and two (04 Mar, 05 Mar) and
quiet to minor storm levels on day three (06 Mar).
