Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 315 Issued at 2200Z on 10 Nov 2020IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been at very low levels for the past 24
hours. The largest solar event of the period was a C1 event observed at
10/1946Z from Region 2781 (S23W23). There are currently 1 numbered
sunspot regions on the disk.
