SDF Number 366 Issued at 2200Z on 31 Dec 2012

IA.  Analysis of Solar Active Regions and Activity from 30/2100Z to
31/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 6 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 (01 Jan, 02 Jan, 03 Jan).

IIA.  Geophysical Activity Summary 30/2100Z to 31/2100Z: 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 483 km/s at
31/0108Z.
