Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 96 Issued at 2200Z on 05 Apr 2020

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: 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 (06 Apr, 07 Apr, 08 Apr).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 449 km/s at 05/0647Z. Total IMF reached 8 nT at
05/0257Z. The maximum southward component of Bz reached -4 nT at
05/0156Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 413 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (06 Apr, 07 Apr, 08
Apr).
