Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 336 Issued at 2200Z on 01 Dec 2012

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
01/1030Z from Region 1620 (S13W95) as it departed the west limb. There
are currently 3 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be at low
levels 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 levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 341 km/s at
01/0403Z. Total IMF reached 9 nT at 01/2038Z. The maximum southward
component of Bz reached -5.1 nT at 01/2020Z. Electrons greater than 2
MeV at geosynchronous orbit reached a peak level of 156 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels for the next two days (02 Dec, 03
Dec). The geomagnetic field is expected to be at quiet levels on 04
December.
