Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 226 Issued at 2200Z on 13 Aug 2020

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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 (14 Aug, 15 Aug, 16 Aug).

IIA.  Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 312 km/s at 12/2109Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 740 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (14 Aug, 15 Aug, 16
Aug).
