Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 317 Issued at 2200Z on 13 Nov 2018

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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 (14 Nov, 15 Nov, 16 Nov).

IIA.  Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 636 km/s at 12/2129Z. Total IMF reached 5 nT at
13/2032Z. The maximum southward component of Bz reached -2 nT at
13/0017Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1803 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (14 Nov, 15 Nov, 16
Nov).
