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 334 Publicado el 2200Z a las 29 Nov 2000IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z Solar activity was low. The largest flare of the past
day was a C9/Sf at 29/0629 UTC in Region 9246 (S12E33). The flare
was associated with an intensity one Type II radio sweep. This is a
rapidly developing D-type sunspot group that has produced several
C-class subflares. Region 9236 (N19W79) continues its decay as it
approaches the west limb and has not produced significant activity
during the past day. The large bushy filament centered at about
S35W45 erupted sometime between 28/1653 UTC and 29/0649 UTC. No
other associated activity was apparent. New Region 9247 (N13E20) was
numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. An isolated M-class flare is possible in either Region
9242 and 9246.
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
The geomagnetic field ranged from unsettled to severe storm levels.
Severe storm conditions were observed at many stations during the
29/0300-0600 UTC period. Solar wind parameters were relatively
benign suggesting that this activity was associated with the
dissipation of energy stored in the geomagnetic field over the past
few days. The greater that 10 MeV proton event ended at 29/0200 UTC
(begin 24/1520 UTC and peak of 942 sfu at 26/2030 UTC).
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active. Active to storm periods are
possible at local night time over the next 24 to 48 hours.
