SDF Number 92 Issued at 2200Z on 01 Apr 2020

IA.  Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: 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 (02 Apr, 03 Apr, 04 Apr).

IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 518 km/s at 31/2106Z.  Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1123 pfu.
