SDF Number 326 Issued at 2200Z on 22 Nov 2019
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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 (23 Nov, 24 Nov, 25 Nov).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 653 km/s at 22/0200Z. Total IMF reached 10
nT at 21/2224Z. The maximum southward component of Bz reached -6 nT at
