SDF Number 229 Issued at 2200Z on 16 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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 (17 Aug, 18 Aug, 19 Aug).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 331 km/s at 16/1516Z. Total IMF reached 8 nT at
16/2056Z. The maximum southward component of Bz reached -6 nT at

a peak level of 382 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (17 Aug, 18 Aug) and quiet to
unsettled levels on day three (19 Aug).
