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 184 Issued at 2200Z on 03 Jul 2010IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was very low during the past 24 hours.
A disappearing filament was observed on EIT near the southwest limb
(S35W65) at 02/2300Z. The SOHO C2 imagery observed a possible CME
associated with this event at 03/0130Z. In addition, an eruption
along a filament channel in the northeast (N35E55) was observed,
along with an EIT wave in the southwest (S40W55). These events
occurred at approximately the same time (03/0830Z) and were also
associated with possible CME events visible on SOHO C2 imagery
around 03/0950Z.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low throughout the forecast period (04-06 July).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet to unsettled as the effects from the
coronal hole high speed stream subsided. 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 mostly quiet throughout the forecast period (04-06
July).
