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 185 Issued at 2200Z on 04 Jul 2010IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z Solar activity was very low. Region 1084 (S19W32) was
quiet and stable. A new, emerging flux region was observed near
N19W38.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels for the next three days (05 - 07 July).
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
The geomagnetic field was quiet. Solar wind velocity was steady at
about 600 km/s through 04/0700Z when speeds gradually decayed to
near 500 km/s by the end of the summary period. 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 for the next three days (05 - 07 July).
