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 316 Issued at 0245Z on 12 Nov 2003 This report is compiled from data received at SWO on 11 Nov

C. Geomagnetic Activity Summary
The geomagnetic field ranged from active to severe storm levels. A single K=7 period was observed at Boulder from 11/0300-0600 UTC. Solar wind conditions of high speed (700-800 km/s) and low density (about 2 p/cc) suggest that the expected coronal hole high-speed stream has arrived.
