Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 125 Issued at 2200Z on 04 May 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 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 (05 May, 06 May, 07 May).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 346 km/s at 04/1148Z. Total IMF reached 9
nT at 03/2111Z. The maximum southward component of Bz reached -5 nT at
03/2321Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 207 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (05 May, 06 May, 07
May).
