Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 54 Issued at 2200Z on 23 Feb 2022IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z 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 (24
Feb, 25 Feb, 26 Feb).
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
