Rapport sur les activités géophysiques
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. Tempêtes de protons
The 10 MeV integral proton flux at geosynchronous
orbit followed a slow rising trend shortly after the end of the east
limb X-flare of 28 December. Flux exceeded event threshold at
29/0510 UTC. Further enhancement in possible association with the
shock passage (described in Part C below) resulted in a peak flux
observation of 76 pfu at 29/0815 UTC. The event ended at 29/2300
UTC.
C. Résumé d'activité géomagnetique
The geomagnetic field was quiet to
active. An L1 shock passage was observed at approximately 29/0440
UTC, and followed by a sudden impulse of 44 nT at 29/0538 UTC.
Predominantly northward IMF orientation following the shock passage
mostly mitigated the potential geomagnetic response to this event,
presumed to have originated from the CME activity of 26 December.
