Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 314 Issued at 2200Z on 10 Nov 2022
IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (11 Nov, 12 Nov, 13 Nov).
IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 347 km/s at 09/2340Z. Total IMF reached 6 nT at 10/1456Z. The maximum southward component of Bz reached -2 nT at 10/1917Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1334 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (11 Nov, 12 Nov) and quiet levels on day three (13 Nov).
