Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 33 Issued at 2200Z on 02 Feb 2021
IA. Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (03 Feb, 04 Feb, 05 Feb).
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 564 km/s at 02/1627Z. Total IMF reached 20
nT at 02/0247Z. The maximum southward component of Bz reached -15 nT at
02/0158Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 350 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (03 Feb) and quiet levels on
days two and three (04 Feb, 05 Feb).
