Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 311 Issued at 2200Z on 06 Nov 2020
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: Solar activity has been at very low levels for the past 24
hours. The largest solar event of the period was a C1 event observed at
06/1522Z from Region 2781 (S23E29). There are currently 2 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (07
Nov, 08 Nov, 09 Nov).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 507 km/s at 06/0838Z. Total IMF reached 10
nT at 06/0413Z. The maximum southward component of Bz reached -6 nT at
06/0417Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1277 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (07 Nov) and quiet levels
on days two and three (08 Nov, 09 Nov).
