Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 338 Issued at 2200Z on 03 Dec 2020

IA.  Analysis of Solar Active Regions and Activity from 02/2100Z to
03/2100Z: Solar activity has been at very low levels for the past 24
hours. 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 and two (04 Dec, 05 Dec)
and expected to be very low with a slight chance for a C-class flare on
day three (06 Dec).

IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 427 km/s at 03/0300Z. Total IMF reached 5 nT at
03/2000Z. The maximum southward component of Bz reached -4 nT at
03/1346Z.  Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 3 pfu at 03/0905Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1127 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (04 Dec, 05 Dec, 06
Dec).
