Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 192 Issued at 2200Z on 10 Jul 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 Jul, 12 Jul, 13 Jul).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 346 km/s at 10/1730Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 224 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (11 Jul) and quiet to unsettled levels
on days two and three (12 Jul, 13 Jul).
