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 191 Issued at 2200Z on 09 Jul 2008IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels for 10 July. Unsettled
to active conditions, with isolated minor storm periods, are
expected for 11-12 July. An increase in activity is expected due to
a recurrent coronal hole high speed stream.
