SDF Number 113 Issued at 2200Z on 22 Apr 2020
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 Apr, 24 Apr, 25 Apr).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 509 km/s at 22/0043Z. Total IMF reached 5
nT at 22/0216Z. The maximum southward component of Bz reached -4 nT at
