SDF Number 275 Issued at 2200Z on 01 Oct 2020
IA. Analysis of Solar Active Regions and Activity from 30/2100Z to
01/2100Z: 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 (02 Oct, 03 Oct, 04 Oct).
IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 578 km/s at 30/2100Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 32431 pfu.
