Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 220 Issued at 2200Z on 07 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: 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 days one, two, and three (08
Aug, 09 Aug, 10 Aug).
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 502 km/s at 06/2244Z. Total IMF reached 5 nT at
07/1113Z. The maximum southward component of Bz reached -3 nT at
06/2327Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1683 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (08 Aug) and quiet levels
on days two and three (09 Aug, 10 Aug).
