SDF Number 229 Issued at 2200Z on 17 Aug 2019
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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 (18 Aug, 19 Aug, 20 Aug).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 387 km/s at 17/0044Z. Total IMF reached 6 nT at
17/1843Z. The maximum southward component of Bz reached -4 nT at

peak level of 1670 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (18 Aug, 19 Aug) and quiet to
unsettled levels on day three (20 Aug).
