SDF Number 3 Issued at 2200Z on 03 Jan 2021
IA. Analysis of Solar Active Regions and Activity from 02/2100Z to
03/2100Z: 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 (04 Jan, 05 Jan, 06 Jan).
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 380 km/s at 02/2327Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 629 pfu.
