Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 36 Issued at 2200Z on 05 Feb 2022

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
04/2157Z from Region 2936 (N17W75). There are currently 5 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (06 Feb,
07 Feb, 08 Feb).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 616 km/s at 05/1938Z. Total IMF reached 8
nT at 05/0740Z. The maximum southward component of Bz reached -7 nT at
05/0751Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2774 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to active levels on day one (06 Feb), quiet to
unsettled levels on day two (07 Feb) and quiet levels on day three (08
Feb).
