SDF Number 232 Issued at 2200Z on 20 Aug 2019
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 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 (21 Aug, 22 Aug, 23 Aug).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 433 km/s at 20/1940Z. Total IMF reached 10 nT at
20/0714Z. The maximum southward component of Bz reached -6 nT at
