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 162 Issued at 2200Z on 11 Jun 2006IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was at very low levels. Region 892
(S07W27) was limited to minor B-class flare activity with slow decay
in the magnetic gamma structure which was evident today. A simply
structured Hsx alpha group emerged during the period and is newly
numbered Region 894 (S07E36).
IB. Solar Activity Forecast
Solar activity is expected to be at
very low levels.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high
levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels throughout the period.
