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 099 Publicado el 2200Z a las 09 APR 1999IA. Análisis de regiones solares activas y de actividad desde 08-2100Z hasta 09-2100Z SOLAR ACTIVITY RETURNED TO LOW LEVELS. REGION 8508
(N23W01) STABILIZED AND PRODUCED SEVERAL LOW LEVEL C-CLASS
SUBFLARES. MIXED POLARITIES REMAINED IN THIS REGION BUT OVERALL THE
REGION BECAME LESS COMPLEX AND MAGNETIC GRADIENTS LESSENED. OTHER
DISK REGIONS WERE STABLE OR DECLINING.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
FOR THE NEXT THREE DAYS. REGION 8508 IS CAPABLE OF PRODUCING AN
ISOLATED M-CLASS EVENT BUT THAT POSSIBILITY IS DECREASING DUE TO
REGION SIMPLIFICATION.
IIA. Resumen de la actividad geofísica 08-2100Z a 09-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. ENERGETIC ELECTRON
FLUXES AT GEOSYNCHRONOUS ORBIT DECREASED TO MODERATE LEVELS DURING
THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD SHOULD
REMAIN AT QUIET TO UNSETTLED LEVELS FOR THE NEXT THREE DAYS.
