Geofysisk rapport
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.

B. Protonstormar
The greater than 10 MeV proton event that began
at 11/1135Z, peaked at 35 pfu at 11/1845Z, and ended at 12/0405Z.
This proton event is likely to be associated with the C9 flare that
occurred at 11/0419Z.
C. Sammanfattning av geofysisk aktivitet
The geomagnetic field was at quiet
to active levels. A shock passage was observed at the ACE
spacecraft at approximately 12/1730Z and it is believed to be in
response to the partial halo CME that was associated with the C2
flare that occurred on 09/2040Z. Once again, the IMF Bz remained
predominantly northward and the geomagnetic response was weak.
Solar wind speeds peaked at near 540 km/s shortly after the shock
passage.
