SDF Number 16 Issued at 2200Z on 16 Jan 2020
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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 (17 Jan, 18 Jan, 19 Jan).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 403 km/s at 16/0949Z. Total IMF reached 7
nT at 16/0201Z. The maximum southward component of Bz reached -4 nT at
