Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 334 Issued at 2200Z on 30 Nov 2021

IA.  Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 5 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 (01 Dec,
02 Dec, 03 Dec).

IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 447 km/s at 30/2055Z. Total IMF reached 15 nT at
30/2038Z. The maximum southward component of Bz reached -12 nT at
30/1947Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 341 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (01 Dec, 02 Dec)
and quiet to active levels on day three (03 Dec).
