Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 317 Issued at 2200Z on 13 Nov 2017

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 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare 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 436 km/s at 12/2307Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 20582 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and three (14 Nov, 16 Nov)
and unsettled to active levels on day two (15 Nov).
