Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 292 Issued at 2200Z on 19 Oct 2022IA. Analysis of Solar Active Regions and Activity from 18-2100Z to 19-2100Z 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
18/2146Z from Region 3124 (S34W68). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
