Report of Solar Geophysical Activity (RSGA)

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 7 Issued at 2200Z on 07 Jan 2013

IA.  Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
07/0852Z from Region 1640 (N28W87). There are currently 12 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be at low
with a chance for moderate levels on days one, two, and three (08 Jan,
09 Jan, 10 Jan).

IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z: 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 385 km/s at
07/1934Z. Total IMF reached 6 nT at 07/0126Z. The maximum southward
component of Bz reached -5.8 nT at 07/0327Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet with a chance of unsettled levels for the next three days
(08 Jan, 09
Jan, 10 Jan).
