Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 23 Issued at 2200Z on 23 Jan 2020
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 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
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 to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 385 km/s at 22/2314Z. Total IMF reached 7
nT at 22/2354Z. The maximum southward component of Bz reached -6 nT at
22/2325Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 143 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (24 Jan, 25 Jan, 26
Jan).
