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 038 Issued at 2200Z on 07 Feb 2010IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was high. Region 1045 (N23W01) produced
two M-class events during the past 24 hours. The first was a M1 at
06/2137Z and the second was a M6/1n at 07/0224Z. The SOHO/LASCO C2
imagery observed a CME off the east limb with the first event and a
full halo with the second event. The M6 x-ray event had an
associated EIT wave, and a Tenflare of 170sfu. This region has
retained a magnetic beta-gamma configuration with a possible delta
magnetic configuration within its interior spots. A new region was
numbered today as Region 1046 (N25E65).
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate with M-class events likely. There is a slight chance
for a X-class event from Region 1045.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled with isolated active conditions for the
next three days (08-10 February) due to a recurrent coronal hole
high speed stream and CME effects.
