Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 297 Issued at 2200Z on 24 Oct 2022IA. 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 C4 event observed at
24/0802Z from Region 3126 (S10W51). There are currently 3 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 Oct,
26 Oct, 27 Oct).
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z

a peak level of 103 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (25 Oct) and quiet levels
on days two and three (26 Oct, 27 Oct).
