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.

******************************** CORRECTED COPY ************************************************ SDF Número 240 Publicado el 2200Z a las 28 AUG 1997IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z SOLAR ACTIVITY WAS VERY LOW. A SERIES OF B-CLASS
EVENTS, THE LARGEST OF WHICH WAS A B9.3, WERE REPORTED. NONE WERE
CORRELATED WITH OPTICAL FLARES. REGION 8076 (N29E24) CONTINUED ITS
GROWTH AND IS NOW A DSI SPOT GROUP IN A BETA-GAMMA CONFIGURATION.
NEW REGION 8079 (N15E10) WAS NUMBERED TODAY. THIS REGION IS
APPROXIMATELY 9 DEGREES SOUTHWEST OF REGION 8078 (N16E12) AND
APPEARS TO BE CONNECTED. HOWEVER, SPACE-BASED X-RAY IMAGES AND
MAGNETIC ANALYSIS INDICATE A TRAILER POLARITY AREA WITHOUT SPOTS
INTERCEDES BETWEEN THE TWO REGIONS, THUS LENDING CREDENCE TO THEIR
SEPARATION.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGION 8076 HAS A GOOD CHANCE OF PRODUCING ADDITIONAL
C-CLASS EVENTS AND AN OUTSIDE CHANCE OF PRODUCING AN ISOLATED
M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
THE GOEMAGNETIC FIELD RANGED FROM QUIET TO MINOR STORMING AT ALL
LATITUDES. ACTIVE TO MINOR STORM LEVELS WERE OBSERVED BETWEEN
28/0300 AND 28/0900Z. THIS DISTURBANCE MAY HAVE BEEN THE RESULT OF A
MODERATELY WELL-PLACE NORTHERN CORONAL HOLE EXTENSION. SPACE-BASED
INSTRUMENTS INDICATE EARTH WAS IN A HIGH SPEED, LOW DENSITY CORONAL
HOLE STREAM AT THE TIME OF THE DISTURBANCE.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE ENTIRE FORECAST PERIOD.
