Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 17 Issued at 2200Z on 17 Jan 2022IA. Analysis of Solar Active Regions and Activity from 16-2100Z to 17-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
17/1415Z from Region 2930 (N21W45). There are currently 7 numbered
sunspot regions on the disk.
