SDF Number 230 Issued at 2200Z on 18 Aug 2019
IA. Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: 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 (19 Aug, 20 Aug, 21 Aug).
IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 383 km/s at 18/1139Z. Total IMF reached 9
nT at 18/0605Z. The maximum southward component of Bz reached -5 nT at
