Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 232 Issued at 2200Z on 20 Aug 2018
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 1 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 to active levels for the past 24 hours. Solar
wind speed reached a peak of 708 km/s at 20/1717Z. Total IMF reached 13
nT at 20/0310Z. The maximum southward component of Bz reached -8 nT at
20/0226Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 14785 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to active levels on day one (21 Aug) and quiet to
active levels on days two and three (22 Aug, 23 Aug).
