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 018 Publicado el 2200Z a las 18 Jan 2005IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was moderate. Region 720 (N13W44)
continued to flare; however, the largest event in the past 24 hours
was an M4/2n at 18/1551 UTC. Although the region remains large and
magnetically complex, further sunspot restructuring and decay is
evident since yesterday. New Region 724 (S12W07) emerged on the
disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be
moderate to high. Region 720, although diminishing in complexity,
still has sufficient potential for another major solar event.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field ranged from unsettled to severe storm levels.
The greater than 10 MeV proton event remains in progress with a
start time of 16/0210 UTC and a peak flux of 5040 pfu observed at
17/1750 UTC. The greater than 100 MeV proton event also remains in
progress with a start time of 17/1215 UTC and a 28 pfu peak flux
observed at 17/1700 UTC. GOES spacecraft electron sensors and ACE
SWEPAM instruments remain affected by the energetic proton event.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to remain at active to severe storm levels for the next 24
to 48 hours. The arrival of the CME associated with the X3 flare on
17 January has not yet been observed but is expected to contribute
to geomagnetic activity over the next 12 to 24 hours. The greater
than 100 MeV proton event is expected to end by early on 19 January,
barring a new major flare. The greater than 10 MeV proton event is
expected to remain in progress through late 19 to early 20 January.
