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 354 Issued at 0245Z on 19 Dec 2004 This report is compiled from data received at SWO on 18 Dec
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
None
B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to active. Active periods due to the continued influence of a geoeffective high speed coronal hole stream. Solar wind speed at ACE has decreased from approximately 640 km/s to 510 km/s.
D. Stratwarm
None.
