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 317 Issued at 0245Z on 12 Nov 2004 This report is compiled from data received at SWO on 11 NovA. Energetic Events

B. Proton Events
The greater than 10 MeV proton event that began
at 07/1910Z remains in progress (currently ranging from 50 - 100
pfu). The maximum so far was 495 pfu at 08/0115Z.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
quiet to minor storm levels. The most disturbed levels followed a
prolonged period of southward Bz between 11/03 - 07Z. Solar wind
speed was elevated between 550 and 650 km/s. A 12 nT sudden impulse
was observed at the geomagnetic field at 11/1714Z. Solar wind plasma
and magnetic field measurements at ACE indicate weak transient flow,
likely from the CME activity on 09 - 10 November.

F. Comments
The greater than 2 MeV electron fluence at geosynchronous orbit was at very high levels.
