Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 72 Issued at 2200Z on 13 Mar 2022IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
13/0323Z from Region 2962 (N27W49). There are currently 4 numbered
sunspot regions on the disk.

field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 580 km/s at 13/1047Z. Total IMF
reached 25 nT at 13/1708Z. The maximum southward component of Bz reached
-18 nT at 13/1636Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 583 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at unsettled to major storm levels on day one (14 Mar), unsettled
to minor storm levels on day two (15 Mar) and quiet to unsettled levels
on day three (16 Mar).
