Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 333 Issued at 2200Z on 29 Nov 2021IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z
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, two, and three (30 Nov,
01 Dec, 02 Dec).
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 397 km/s at 29/0515Z. Total IMF reached 9
nT at 28/2326Z. The maximum southward component of Bz reached -7 nT at
29/0123Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 214 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (30 Nov, 01 Dec, 02
Dec).
