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 366 Issued at 0245Z on 31 Dec 2004 This report is compiled from data received at SWO on 30 Dec

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels today. The elevated periods are most likely due to a waning high speed coronal hole stream.
