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 048 Publicado el 2200Z a las 17 FEB 2000IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z SOLAR ACTIVITY WAS MODERATE. AN M2/1B ACCOMPANIED BY A
TYPE II RADIO SWEEP OCCURRED AT 17/1852UT FROM REGION 8869 (S22W21).
AN M1 EVENT OCCURRED AT 17/2035UT ACCOMPANIED BY A 200 SFU TENFLARE.
THIS EVENT WAS REPORTED TO OCCUR IN REGION 8872 (S29E02). THE
OPTICAL OBSERVATORY WAS UNABLE OF DETERMINE THE SIZE AND INTENSITY
OF THE FLARE DUE TO POOR SEEING CONDITIONS. BOTH EVENTS PRODUCED
DISAPPEARING SOLAR FILAMENTS AS WELL. THESE EVENTS WERE SOMEWHAT
UNEXPECTED AS THE REGIONS SHOWED VERY LITTLE ACTIVITY PRIOR TO
FLARING. THE REST OF THE DISK AND LIMBS WERE MOSTLY QUIET AND
STABLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
WITH AN ISOLATED CHANCE OF M-CLASS EVENTS.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO CONTINUE TO BE QUIET TO UNSETTLED FOR THE FIRST PART OF
THE PERIOD. ACTIVITY COULD INCREASE ON THE THIRD DAY DUE TO THE M2
AND M1 EVENTS THAT OCCURRED DURING THIS PERIOD.
