Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 319 Issued at 2200Z on 15 Nov 2015

IA.  Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 4 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (16 Nov,
17 Nov, 18 Nov).

IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
467 km/s at 14/2154Z. Total IMF reached 9 nT at 15/1611Z. The maximum
southward component of Bz reached -6 nT at 15/2057Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 2086 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (16 Nov, 17 Nov)
and quiet to active levels on day three (18 Nov).
