Issued: 2012 Feb 06 2200 UTC
Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Weather Prediction Center and the U.S. Air Force.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 037 Issued at 2200Z on 06 Feb 2012

IA.  Analysis of Solar Active Regions and Activity from  05/2100Z
to 06/2100Z:  Solar activity was moderate. Region 1410 (N17W67)
produced an M1 x-ray flare at 06/2000Z.
IB.  Solar Activity Forecast:  Solar activity is likely to be low
with a chance for moderate levels from Region 1410 for days 1 and 2
(7-8 February). Very low to low level are expected on day 3 (9
February) after Region 1410 transits off the west limb of the solar
disk.
IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field was mostly quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet for days 1-2 (7-8 February). Activity
should increase to unsettled and active levels late on day 3 (9
February) from the onset of coronal hole high speed stream effects.
