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 233 Publicado el 2200Z a las 21 AUG 1998IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY BECAME LOW. REGION 8307 (N31E47)
PRODUCED A C1/SF FLARE AT 21/1620Z. SEVERAL OTHER SMALL TO MID
C-CLASS EVENTS OCCURRED BUT WERE NOT OPTICALLY CORRELATED WITH A
SPECIFIC REGION. CONFLICTING DATA HAVE BEEN RECEIVED REGARDING THE
GROWTH OR DECAY OF REGION 8307. TIGHT MAGNETIC GRADIENTS REMAINED IN
THIS REGION BUT BY TECHNICAL DEFINITION, THE DELTA CONFIGURATION
FADED. VECTOR MAGNETOGRAPH DATA ON REGION 8307 FROM 20 AUG DID NOT
SHOW LARGE AREAS OF HIGH SHEAR.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD BE GENERALLY LOW
TO MODERATE. REGION 8307 HAS SHOWN ITS CAPABILITY OF PRODUCING
X-CLASS EVENTS AND MORE REMAIN POSSIBLE. HOWEVER, RECENT TRENDS
INDICATE A LESSENING IN THE RATE OF FLARE PRODUCTION FROM THIS
REGION.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. SOLAR WIND DATA SHOW A
LOW VELOCITY FLOW IN THE EARTH'S VICINITY WITH PREDOMINANTLY
NORTHWARD BZ.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD SHOULD BE
QUIET TO SLIGHTLY ACTIVE FOR THE NEXT THREE DAYS. AN EQUATORWARD
EXTENSION OF THE NORTHERN POLAR CORONAL HOLE IS EXPECTED TO BEGIN TO
DISTURB THE GEOMAGNETIC FIELD DURING THE PERIOD.
