Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 156 Issued at 2200Z on 04 Jun 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
with a slight chance for a C-class flare on days one, two, and three (05
Jun, 06 Jun, 07 Jun).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 355 km/s at 04/2017Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 146 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (05 Jun) and quiet to unsettled levels
on days two and three (06 Jun, 07 Jun).
