Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 225 Issued at 2200Z on 12 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 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 (13
Aug, 14 Aug, 15 Aug).
IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 330 km/s at 12/0745Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1575 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (13 Aug, 14 Aug, 15
Aug).
