Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 84 Issued at 2200Z on 24 Mar 2020

IA.  Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: 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 (25 Mar, 26 Mar, 27 Mar).

IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 494 km/s at 23/2105Z. Total IMF reached 5
nT at 24/0017Z. The maximum southward component of Bz reached -3 nT at
24/0021Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1303 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (25 Mar, 26 Mar, 27
Mar).
