Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 333 Issued at 2200Z on 28 Nov 2020
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: Solar activity has been at low levels for the past 24 hours.
There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (29 Nov,
30 Nov, 01 Dec).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 487 km/s at 28/0004Z. Total IMF reached 6
nT at 28/1454Z. The maximum southward component of Bz reached -5 nT at
28/0139Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1673 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (29 Nov, 30 Nov, 01
Dec).
