Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 31 Issued at 2200Z on 31 Jan 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 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 (01 Feb, 02 Feb, 03 Feb).
IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 557 km/s at 31/0933Z. Total IMF reached 8
nT at 31/0221Z. The maximum southward component of Bz reached -6 nT at
31/0215Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 334 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (01 Feb) and quiet levels on
days two and three (02 Feb, 03 Feb).
