Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 152 Issued at 2200Z on 01 Jun 2022

IA.  Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 4 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (02 Jun, 03 Jun, 04 Jun).

IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 527 km/s at 01/0301Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 6865 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (02 Jun, 03 Jun, 04
Jun).
