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 219 Issued at 2200Z on 07 Aug 2006IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. No new regions were
numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field ranged from quiet to major storm conditions.
Activity was due to a solar sector boundary crossing followed by a
coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue to be quiet to active with minor storm periods
possible at higher latitudes on 08 August. On 09 and 10 August,
conditions are expected to be quiet to unsettled.
