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 05 Jul 2004IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was very low. Region 639 (N08W35)
produced a number of small flares, the largest a B2/Sf at 05/1554
UTC. All regions currently on the disk are small and in an apparent
state of decay.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit briefly reached high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
