Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 340 Issued at 2200Z on 05 Dec 2012

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: 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
05/0028Z from New Region 1628 (N10E65). There are currently 5 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be at very
low to low levels on days one, two, and three (06 Dec, 07 Dec, 08 Dec).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: 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 421 km/s at
04/2120Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (06 Dec, 07 Dec, 08 Dec).
