Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 162 Issued at 2200Z on 10 Jun 2020

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: 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
on days one, two, and three (11 Jun, 12 Jun, 13 Jun).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 504 km/s at 10/1256Z. Total IMF reached 7
nT at 10/0437Z. The maximum southward component of Bz reached -6 nT at
10/0426Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 124 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Jun, 12 Jun, 13
Jun).
