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 192 Issued at 2200Z on 10 Jul 2008IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been very low. The visible solar
disk remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at unsettled to active levels for 11-12 July with a
chance for isolated minor storm conditions possible due to a coronal
hole high speed stream. Activity levels for 13 July is expected to
be mostly unsettled levels with a chance for isolated active
periods.
