Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 236 Issued at 2200Z on 24 Aug 2022IA. 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 3 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 (25 Aug,
26 Aug, 27 Aug).
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
