Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 55 Issued at 2200Z on 24 Feb 2022

IA.  Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (25
Feb, 26 Feb, 27 Feb).

IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 548 km/s at 24/0443Z. Total IMF reached 7
nT at 24/1953Z. The maximum southward component of Bz reached -5 nT at
23/2309Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 917 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and three (25 Feb, 27 Feb) and quiet
to unsettled levels on day two (26 Feb).
