Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 98 Issued at 2200Z on 07 Apr 2020

IA.  Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: 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 (08 Apr, 09 Apr, 10 Apr).

IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 340 km/s at 07/0345Z. Total IMF reached 6 nT at
07/2039Z. The maximum southward component of Bz reached -5 nT at
07/2025Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 606 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (08 Apr, 09 Apr) and quiet to
unsettled levels on day three (10 Apr).
