Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 340 Issued at 2200Z on 06 Dec 2013

IA.  Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
06/0648Z from Region 1909 (S17W50). There are currently 6 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (07
Dec, 08 Dec, 09 Dec).

IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 358 km/s at
06/0014Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 158 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (07 Dec, 08 Dec) and
quiet levels on day three (09 Dec).
