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 013 Issued at 2200Z on 13 Jan 2006

IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z

Solar activity was very low. A nine degree disappearing solar filament centered at S05W19 occurred at approximately 12/2340Z as seen from H-alpha and EIT imagery. A Type II radio sweep began at 13/0004Z with an estimated shock speed of approximately 500 km/sec. LASCO C2 imagery showed a CME on the west limb beginning at 13/0054Z which does not appear to be Earth directed. No sunspots are visible on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
