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 325 Publicado el 2200Z a las 21 NOV 1997IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY WAS LOW. REGION 8108 (N19W21) PRODUCED
SEVERAL LOW C-CLASS SUBFLARES. DURING THE PERIOD, THIS REGION, GREW
SLIGHTLY AND A MAGNETIC DELTA CONFIGURATION FORMED IN THE LEADER.
PREVIOUS MIXED POLARITIES REMAINED. SPACE-BASED IMAGERS SHOWED A
BROAD AREA OF EMISSION OVER THE SOUTHEAST LIMB WHERE OLD REGION 8100
IS DUE TO RETURN.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD BE GENERALLY
LOW. REGION 8108 HAS THE CAPABILITY OF PRODUCING ISOLATED M-CLASS
EVENTS. OLD REGION 8100 IS NOT EXPECTED TO BE AS ACTIVE AS LAST
ROTATION BUT UNTIL BETTER VIEWED, IT MUST BE CONSIDERED A CANDIDATE
FOR ISOLATED M-CLASS EVENTS.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES. RECENT SOLAR WIND
DATA SHOW A VERY SLOW FLOW IN THE EARTH'S NEIGHBORHOOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
FORECAST TO BE QUIET TO ACTIVE FOR THE NEXT THREE DAYS. ISOLATED
MINOR STORM CONDITIONS ARE POSSIBLE ON 23 NOV FROM A VERY LONG
DURATION X-RAY EVENT OBSERVED NEAR CENTRAL MERIDIAN ON 19 NOV.
