Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 214 Issued at 2200Z on 01 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: 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
on days one, two, and three (02 Aug, 03 Aug, 04 Aug).
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 358 km/s at 01/0023Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 226 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (02 Aug), quiet to unsettled
levels on day two (03 Aug) and quiet levels on day three (04 Aug).
