Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 53 Issued at 2200Z on 22 Feb 2022

IA.  Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 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 (23
Feb, 24 Feb, 25 Feb).

IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 591 km/s at 22/0102Z. Total IMF
reached 6 nT at 22/0518Z. The maximum southward component of Bz reached
-5 nT at 22/0613Z.  Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 553 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (23 Feb) and quiet levels
on days two and three (24 Feb, 25 Feb).
