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 169 Publicado el 2200Z a las 18 JUN 1999IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY RETURNED TO LOW LEVELS. THE LARGEST
EVENT OF THE PERIOD WAS A C7/1N FROM REGION 8585 (N38E05). SEVERAL
OTHER SMALL TO MIDDLE LEVEL C-CLASS EVENTS WERE OBSERVED. SOHO DATA
INDICATED THAT MOST OF THESE EVENTS WERE FROM BEYOND THE NORTHWEST
LIMB. HOWEVER, A MODERATE DURATION C5 X-RAY EVENT WAS OBSERVED AT
18/1657Z THAT CORRELATED WITH A FLARE BRIGHT MOUND NEAR NE25. LAST
ROTATION, THIS AREA WAS COMPRISED OF SEVERAL ACTIVE REGIONS THAT
PRODUCED FREQUENT C-CLASS AND OCCASIONAL M-CLASS EVENTS. OTHER DISK
REGIONS EXHIBITED ONLY MINOR EVOLUTION.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD BE GENERALLY LOW
FOR THE NEXT THREE DAYS. M-CLASS EVENTS ARE POSSIBLE FROM THE AREA
ROTATING OVER THE NORTHEAST LIMB. A BETTER DETERMINATION OF THE
FLARE POTENTIAL OF THIS AREA MUST AWAIT ITS APPEARANCE TO THE
VISIBLE DISK.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT THREE DAYS.
