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 193 Issued at 2200Z on 12 Jul 2006IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z Solar activity was very low. No new regions were
numbered today.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic field was quiet to active. Activity was due to a
coronal hole high speed stream moving into geoeffective position
late on 11 July. Solar wind speed at ACE is currently elevated
around 510 km/s.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
