Informe geofísico
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. Eventos de Protones
The greater than 10 MeV proton flux at
geosynchronous orbit has fluctuated near the event threshold value
of 10 pfu for most of the day, though now appears to be undergoing
an enhancement due to the recent shock passage. As a result of
near-threshold activity, a 10 MeV proton event has been in progress
since 30/0245 UTC. Max flux observed today is 19 pfu, at 30/2355
UTC.
C. Resumen de Actividad Geomagnética
Geomagnetic field activity has
been quiet to active. Most of the day was dominated by ongoing
effects from yesterday's shock passage, with an extended period of
southward IMF producing active conditions during 30/0300-0900 UTC.
Active conditions returned late in the day, when an additional shock
passage was observed at the ACE satellite at 30/1932 UTC, followed
by a sudden impulse of 27 nT observed at Boulder at 30/2010 UTC.
This event is presumed to be an early arrival of effects from the
powerful X-class event of 28 December.
