Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 366 Issued at 2200Z on 31 Dec 2020
IA. Analysis of Solar Active Regions and Activity from 30/2100Z to
31/2100Z: Solar activity has been at very 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 slight chance for a C-class flare on days one and two (01 Jan, 02
Jan) and expected to be very low on day three (03 Jan).
IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 498 km/s at 30/2114Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 560 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (01 Jan, 02 Jan) and quiet to
unsettled levels on day three (03 Jan).
