Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 93 Issued at 2200Z on 02 Apr 2020

IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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 (03 Apr, 04 Apr, 05 Apr).

IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 450 km/s at 02/0659Z. Total IMF reached 6 nT at
02/2026Z. The maximum southward component of Bz reached -5 nT at
02/1921Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1691 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (03 Apr, 05
Apr) and quiet levels on day two (04 Apr).
