Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 214 Issued at 2200Z on 02 Aug 2018

IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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 (03 Aug, 04 Aug, 05 Aug).

IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 404 km/s at 02/0316Z. Total IMF reached 8
nT at 02/0516Z. The maximum southward component of Bz reached -3 nT at
02/0016Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 325 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (03 Aug,
04 Aug, 05 Aug).
