Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 23 Issued at 2200Z on 23 Jan 2021
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: 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 (24
Jan, 25 Jan, 26 Jan).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 374 km/s at 23/2035Z. Total IMF reached 8 nT at
23/2026Z. The maximum southward component of Bz reached -6 nT at
23/2023Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 224 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (24 Jan, 25 Jan)
and quiet levels on day three (26 Jan).
