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 142 Publicado el 2200Z a las 21 MAY 2000IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY REMAINED AT LOW LEVELS. OCCASIONAL
C-CLASS SUBFLARES OCCURRED. REGION 8996 (S21W49) DECREASED IN AREA
BY VIRTUE OF PENUMBRAL DECAY, BUT WAS THE MOST FLARE-PRODUCTIVE OF
THE VISIBLE REGIONS. HOWEVER, REGION 8998 (S12W33) WAS RESPONSIBLE
FOR THE LARGEST FLARE OF THE PERIOD - A C8/SF AT 21/1023Z. THIS
REGION SHOWED NO SIGNIFICANT CHANGE DURING THE PERIOD AND WAS OF
MODERATE SIZE AND MAGNETIC COMPLEXITY. NO SIGNIFICANT CHANGES WERE
REPORTED IN THE REMAINING REGIONS.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE AT
LOW TO MODERATE LEVELS. OCCASIONAL C-CLASS FLARES ARE EXPECTED.
ISOLATED M-CLASS FLARES ARE POSSIBLE.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
GEOMAGNETIC FIELD ACTIVITY WAS AT QUIET TO UNSETTLED LEVELS. PROTON
AND ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT REMAINED AT BACKGROUND
LEVELS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT QUIET TO UNSETTLED LEVELS DURING MOST OF THE
PERIOD WITH A CHANCE FOR ACTIVE LEVELS ON 23 MAY. PROTON AND
ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT ARE EXPECTED TO REMAIN AT
BACKGROUND LEVELS.
