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 042 Issued at 2200Z on 11 Feb 2006

IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z

Solar activity was very low. LASCO imagery showed a CME on the SE limb beginning at about 10/2330Z which does not appear to be Earth directed. One spot remains visible in Region 853 (S09W78).
IB. Solar Activity Forecast
Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet to unsettled due to a recurrent coronal hole.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled. Quiet conditions should return on 13 Feb.
