Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 305 Issued at 2200Z on 01 Nov 2026

IA.  Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: Solar activity has been at low levels for the past 24 hours.
There are currently 2 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 (02 Nov,
03 Nov, 04 Nov).

IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 725 km/s at 01/0313Z. Total IMF
reached 9 nT at 31/2151Z. The maximum southward component of Bz reached
-7 nT at 31/2304Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 5350 pfu at 01/1550Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (02 Nov) and quiet levels
on days two and three (03 Nov, 04 Nov).
