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 026 Issued at 2200Z on 26 Jan 2010IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity was very low. Region 1042 (N18W86)
produced several B-class events during the past 24 hours, the
largest of which was a B6.7 at 1751Z. Region 1041 (S24W03) was
quiet and stable during the last 24 hours.
