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 105 Publicado el 2200Z a las 15 APR 1998IA. Análisis de regiones solares activas y de actividad desde 14-2100Z hasta 15-2100Z SOLAR ACTIVITY WAS LOW. REGION 8203 (N31W24) GREW IN
WHITE LIGHT AND H-ALPHA AND IS NOW A SMALL D-TYPE SUNSPOT GROUP WITH
EMBEDDED ARCH-FILAMENTS. THE REGION PRODUCED A C8/SF AT 0746Z, A
C8/SF AT 1233Z, AND TOGETHER WITH REGION 8198 (S29W31), A C9 X-RAY
BURST AT 1511Z. FREQUENT DISCRETE RADIO BURSTS OCCURRED EARLY IN THE
PERIOD. THE REST OF THE DISK AND LIMBS WERE QUIET.
