SDF Number 328 Issued at 2200Z on 23 Nov 2024IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
23/1607Z from Region 3901 (S06W08). There are currently 10 numbered
