Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 316 Issued at 2200Z on 12 Nov 2018

IA.  Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: 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 (13 Nov, 14 Nov, 15 Nov).

IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 652 km/s at 12/1929Z. Total IMF reached 6
nT at 12/1408Z. The maximum southward component of Bz reached -4 nT at
12/0530Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1208 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (13 Nov) and quiet levels
on days two and three (14 Nov, 15 Nov).
