Informe actividad solar
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.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 339 Publicado el 2200Z a las 05 Dec 2003IA. Análisis de regiones solares activas y de actividad desde 04-2100Z hasta 05-2100Z Solar activity was at low levels. Activity consisted
of minor C-class flares, the largest a C2 flare at 1019Z from Region
513 (N12W47). Region 517 (S06E07) is in a gradual decay phase,
decreasing slightly in area size from yesterday.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels.
IIA. Resumen de la actividad geofísica 04-2100Z a 05-2100Z
The geomagnetic field ranged from quiet to minor storm levels. At
approximately 0200Z the total field measurement of the
interplanetary magnetic field (IMF) increased to 20 nT. The Bz
component of the IMF, after an initial northward direction, turned
southward for nearly ten hours, then began a north-south
oscillation. This signature is similar to that of a co-rotating
interaction region preceding the onset of a high speed stream, but
may include transient effects from a faint halo CME that occurred on
02 December. The ten hour period of southward Bz, together with
solar wind speed near 475 km/s produced minor storm levels for most
of the day.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at unsettled to active conditions. Isolated periods
of minor storm levels are possible on 06-07 December. By 08
December, activity is expected to return to quiet to unsettled
conditions.
