Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 224 Issued at 2200Z on 11 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: 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 (12 Aug, 13 Aug, 14 Aug).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 340 km/s at 11/0508Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 2408 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (12 Aug, 13 Aug, 14
