Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 95 Issued at 2200Z on 04 Apr 2020

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: 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 (05 Apr, 06 Apr, 07 Apr).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 460 km/s at 04/0238Z. Total IMF reached 6
nT at 03/2324Z. The maximum southward component of Bz reached -5 nT at
03/2113Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 448 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (05 Apr) and quiet levels
on days two and three (06 Apr, 07 Apr).
