Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 335 Issued at 2200Z on 01 Dec 2013

IA.  Analysis of Solar Active Regions and Activity from 30/2100Z to
01/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
01/1121Z. There are currently 5 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (02 Dec,
03 Dec, 04 Dec).

IIA.  Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
585 km/s at 01/0255Z. Total IMF reached 14 nT at 01/0040Z. The maximum
southward component of Bz reached -11 nT at 30/2116Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (02 Dec), quiet to unsettled
levels on day two (03 Dec) and quiet levels on day three (04 Dec).
