Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 22 Issued at 2200Z on 22 Jan 2021
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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 slight chance for a C-class flare on days one, two, and three (23
Jan, 24 Jan, 25 Jan).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 358 km/s at 22/1900Z. Total IMF reached 6 nT at
22/1627Z. The maximum southward component of Bz reached -4 nT at
22/1433Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 120 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (23 Jan) and quiet to unsettled levels
on days two and three (24 Jan, 25 Jan).
