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 003 Publicado el 2200Z a las 03 JAN 1999IA. Análisis de regiones solares activas y de actividad desde 02-2100Z hasta 03-2100Z SOLAR ACTIVITY INCREASED, BUT REMAINED AT LOW LEVELS.
TODAY'S MOST ENERGETIC EVENT WAS A LONG-DURATION C6/1N FLARE FROM
REGION 8422 (S23W50) ASSOCIATED WITH AN 18-DEGREE FILAMENT
DISAPPEARANCE AND A WEAK TYPE II RADIO SWEEP. OBSERVATORIES REPORTED
SIGNIFICANT MOVEMENT WITHIN THE FILAMENT FOR SEVERAL HOURS PRIOR TO
THE DISAPPEARANCE. HOWEVER, REGION 8422 SHOWED NO SIGNIFICANT
CHANGES AND REMAINED A SMALL, SIMPLE SPOT GROUP. REGION 8421
(N26W65) SIMPLIFIED SLIGHTLY, BUT REMAINED A LARGE, MAGNETICALLY
COMPLEX GROUP. IT PRODUCED AN ISOLATED C-CLASS SUBFLARE LATE IN THE
PERIOD, BUT WAS OTHERWISE STABLE. NEW REGION 8430 (S25E50) WAS
NUMBERED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8421 MAY PRODUCE AN ISOLATED M-CLASS FLARE.
THERE IS ALSO A SLIGHT CHANCE FOR A MAJOR FLARE FROM THIS REGION.
IIA. Resumen de la actividad geofísica 02-2100Z a 03-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT MOSTLY QUIET LEVELS THROUGH THE PERIOD.
