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 187 Issued at 2200Z on 06 Jul 2010IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z
Solar activity was very low during the past 24 hours. A
long duration B1 flare began at 05/1836Z, peaked at 06/0024Z, and
ended at 06/0312Z. This event was associated with a CME observed in
SOHO LASCO C2 imagery, lifting off the NW limb at 05/2108Z. The
source of this CME appeared to be a filament eruption, observed in
SOHO EIT imagery at 05/1751Z on the NW limb near N26. This CME does
not appear to be earth-directed. A second filament eruption occurred
near N36E16, observed in SOHO EIT imagery at 06/0400Z. Region 1086
(N18W65) produced a B1 flare at 06/1011Z.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low for the next three days.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the past 24
hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominantly quiet for the next three days (07-09
July). Isolated unsettled levels are expected at high latitudes on
day three (09 July).
