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 189 Issued at 2200Z on 08 Jul 2010IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z
Solar activity was very low. The SOHO/LASCO EIT
imagery observed a faint eruption along a filament channel
approaching the northwest limb. A CME was observed on the C2
imagery following this event around 08/1630Z. The CME is not
expected to be earth directed. Several B-class flares were observed
during the last 24 hours which are associated with a loop structured
region approaching the northeast limb (old Region 1083 N19, L=331).
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a slight chance for a C-class event.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet with isolated unsettled levels for day
one (09 July) due to a recurrent coronal hole high speed stream.
Quiet conditions are expected for days two and three (10-11 July).
