Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 299 Issued at 2200Z on 26 Oct 2022IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
26/1243Z from Region 3133 (N26E60). There are currently 5 numbered
