SDF Number 237 Issued at 2200Z on 24 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (25 Aug, 26 Aug, 27 Aug).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 415 km/s at 24/0214Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 179 pfu.
