Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 284 Issued at 2200Z on 10 Oct 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 2 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 (11
Oct, 12 Oct, 13 Oct).
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 309 km/s at 10/1039Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1243 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Oct, 12 Oct, 13
Oct).
