Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 309 Issued at 2200Z on 04 Nov 2020
IA. Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: 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
04/0442Z from Region 2781 (S25E55). There are currently 1 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 (05 Nov,
06 Nov, 07 Nov).
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 370 km/s at 04/0544Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 955 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (05 Nov) and quiet to unsettled levels
on days two and three (06 Nov, 07 Nov).
