SDF Number 310 Issued at 2200Z on 06 Nov 2021IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
05/2157Z from Region 2894 (S27E66). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (07 Nov,
08 Nov, 09 Nov).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z

wind speed reached a peak of 634 km/s at 06/0132Z. Total IMF reached 10
nT at 06/0006Z. The maximum southward component of Bz reached -4 nT at
06/1606Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1633 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (07 Nov, 08 Nov)
and quiet levels on day three (09 Nov).
