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 250 Publicado el 2200Z a las 07 Sep 2002IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity was low. Only a few C-class flares
occurred. New Region 105 (S06E77) is currently rotating around the
east limb and appears to be the return of old active Region 69 (S08,
L=299). So far the area has not produced significant activity. New
Region 104 (N11E59) was also numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Region 105 is the most likely source of energetic
flares.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
The geomagnetic field ranged from quiet to severe storm levels. A
shock in the solar wind was observed by the NASA ACE spacecraft at
07/1609 UTC and was followed by a 7 nT sudden impulse on the Boulder
magnetometer at 07/1638 UTC. This shock is believed to be related to
the eruptive filament and CME which occurred on 05 September. The
greater than 10 MeV proton flux crossed the 10 pfu event threshold
at 07/0440 UTC after a slow rise over the previous 28 hours. Peak
event flux so far was 208 pfu at 07/1650 UTC. Retrospect analysis
suggests that these particles are most likely associated with the
eruptive filament mentioned above rather than a west limb event as
suggested yesterday.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at active to storm levels over the next 24 hours,
becoming quiet to unsettled by 10 September. The greater than 10 MeV
proton event is expected to end by 09 September.
