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.

SGAS Number 267 Issued at 0245Z on 23 Sep 2004 This report is compiled from data received at SWO on 22 SepA. 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
unsettled with a single occurrence of minor storming at 1500Z.
Active levels were observed from 1500Z to 1800Z. The minor storm
levels were attributed to a CME from an M-class flare on 19
September. Solar wind speed increased to approximately 530 km/s
from 1850Z to 2045Z. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels today.
D. Stratwarm
None.
