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 192 Issued at 2200Z on 10 Jul 2004IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was very low. New Region 644 (N11E69)
rotated into view as a single H-type sunspot. Region 645 (N12W11)
emerged on the disk. Another new region, not yet numbered, is
rotating onto the disk near southeast 13. This region is fairly
bright in X-rays and appears to have raised the background x-ray
flux from B1 to about B4.
IB. Solar Activity Forecast
Solar activity is expected to be low.
The chance of a small M-class flare is expected to increase as the
new east limb regions fully rotate onto the disk.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
