Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 287 Issued at 2200Z on 14 Oct 2022
IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: 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 14/0944Z from Region 3112 (N23W92). There are currently 4 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 day one (15 Oct) and likely to be low with a slight chance for an M-class flare on days two and three (16 Oct, 17 Oct).
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 489 km/s at 14/2046Z. Total IMF reached 18 nT at 14/1340Z. The maximum southward component of Bz reached -14 nT at 14/0828Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2335 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (15 Oct), quiet to unsettled levels on day two (16 Oct) and quiet levels on day three (17 Oct).
