Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 281 Issued at 2200Z on 08 Oct 2022IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z 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
08/0040Z from Region 3112 (N22W16). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (09 Oct, 10 Oct, 11 Oct).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 553 km/s at 08/1722Z. Total IMF reached 6
nT at 08/0410Z. The maximum southward component of Bz reached -5 nT at
