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 291 Publicado el 2200Z a las 18 OCT 1999IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY CONTINUED AT LOW LEVELS. REGION 8731
(N13W33) SHOWED A SMALL INCREASE IN SPOT COUNT AND REMAINED A LARGE,
MAGNETICALLY COMPLEX REGION. IT PRODUCED ISOLATED C-CLASS SUBFLARES
DURING THE PERIOD. NO SIGNIFICANT CHANGES WERE OBSERVED IN THE
REMAINING REGIONS AND NO NEW REGIONS WERE ASSIGNED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE AT
LOW TO MODERATE LEVELS. REGION 8731, THOUGH RELATIVELY INACTIVE
DURING THE PAST FEW DAYS, STILL APPEARS CAPABLE OF M-CLASS FLARE
PRODUCTION. THERE IS A SLIGHT CHANCE FOR A MAJOR FLARE FROM THIS
REGION AS WELL.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
GEOMAGNETIC FIELD ACTIVITY WAS AT QUIET TO UNSETTLED LEVELS. THE
GREATER THAN 2 MEV ELECTRON FLUX REMAINED AT MODERATE TO HIGH
LEVELS.
IIB. Pronóstico de la actividad geofísica
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO REMAIN AT QUIET TO UNSETTLED LEVELS DURING THE FIRST TWO
DAYS OF THE PERIOD. ACTIVITY IS EXPECTED TO INCREASE TO UNSETTLED TO
ACTIVE LEVELS ON THE FINAL DAY DUE TO CORONAL HOLE EFFECTS. THE
GREATER THAN 2 MEV ELECTRON FLUX IS EXPECTED TO REMAIN AT MODERATE
TO HIGH LEVELS.
