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 018 Issued at 0245Z on 18 Jan 2004 This report is compiled from data received at SWO on 17 JanA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1735 1750 1759 0540 M5.0 270000 580 II
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. A coronal hole high speed stream is responsible for the weak
disturbed periods. The IMF Bz was predominantly northward which
offset the geomagnetic effects of the high speed flow.
D. Stratwarm
None
