Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 311 Issued at 2200Z on 07 Nov 2018

IA.  Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: 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 (08 Nov, 09 Nov, 10 Nov).

IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 459 km/s at 07/1835Z. Total IMF reached 7
nT at 07/1756Z. The maximum southward component of Bz reached -6 nT at
07/1832Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 10832 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (08 Nov) and quiet to minor storm
levels on days two and three (09 Nov, 10 Nov).
