Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

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