Geophysical 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.

C. Geomagnetic Activity Summary
The geomagnetic field was at
predominantly quiet to unsettled levels. There was an isolated
active period that occurred between 28/0600 and 0900Z in response to
southward Bz oscillations in the interplanetary magnetic field.

F. Comments
The ACE spacecraft orbit will bring ACE to its closest approach with the Sun on August 30, 2004. During that time possible solar radio noise may interfere with spacecraft telemetry resulting in the loss of real time solar wind plasma, magnetic field, and particle data.
