Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 283 Issued at 2200Z on 10 Oct 2022

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
10/1628Z from Region 3112 (N22W41). There are currently 5 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (11 Oct, 12 Oct,
13 Oct).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 632 km/s at 09/2320Z. Total IMF reached 5
nT at 10/0453Z. The maximum southward component of Bz reached -5 nT at
10/0843Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 3586 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (11 Oct), quiet to active
levels on day two (12 Oct) and quiet levels on day three (13 Oct).
