Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 223 Issued at 2200Z on 10 Aug 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
with a slight chance for a C-class flare on day one (11 Aug) and
expected to be very low on days two and three (12 Aug, 13 Aug).
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 384 km/s at 09/2239Z. Total IMF reached 5 nT at
10/0023Z. The maximum southward component of Bz reached -3 nT at
09/2245Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2586 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Aug, 12 Aug, 13
Aug).
