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.

SDF Number 037 Issued at 2200Z on 06 Feb 2010

IA. 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.
