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.

Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 074 Issued at 0245Z on 14 Mar 2004 This report is compiled from data received at SWO on 13 MarA. Energetic Events

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
quiet to active. The high speed coronal hole stream that produced
several minor storm periods in recent days is now subsiding. Solar
wind speed decreased to below 500 km/s by the end of the period.
