Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 158 Issued at 2200Z on 06 Jun 2020

IA.  Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: 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 (07
Jun, 08 Jun, 09 Jun).

IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 331 km/s at 05/2159Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 191 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (07 Jun, 08 Jun, 09
Jun).
