SDF Number 354 Issued at 2200Z on 20 Dec 2017
IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (21 Dec, 22 Dec, 23 Dec).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 505 km/s at 19/2200Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 4134 pfu.
