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 2010IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity was moderate. A new region emerged at a
rapid pace today and was numbered Region 1045 (N24E15). The region
produced several C-class events and a M2/Sn event at 06/1859Z. The
region has grown to around 290 millionths of white light area
coverage with a magnetic beta-gamma configuration and a possible
delta magnetic configuration within its interior spots.
IB. Solar Activity Forecast
Solar activity is expected to be low
with a chance for an M-class event.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled with isolated active conditions, and a
slight chance for isolated minor storming for the next three days
(07-09 February). The increase in activity is expected due to CME
activity from 02-03 February and a recurrent coronal hole high speed
stream.
