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

IA.  Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: 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
24/0237Z. There are currently 2 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (25 Jan,
26 Jan, 27 Jan).

IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 344 km/s at 23/2333Z. Total IMF reached 10 nT at
24/2048Z. The maximum southward component of Bz reached -5 nT at
24/2100Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 10023 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (25 Jan, 27
Jan) and quiet to active levels on day two (26 Jan).
