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 332 Publicado el 2200Z a las 28 NOV 1999IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8771 (S15W85)
PRODUCED AN M3/SN AT 28/0146UT AND AN M1/SF AT 28/0557UT. LIMB
OBSERVATIONS SUGGESTS THAT THIS REGION WAS ALSO RESPONSIBLE FOR A
LONG-DURATION M1 X-RAY FLARE WHICH STARTED AT 28/1800UT AND PEAKED
AT 1917UT. LIMB PROXIMITY IS MAKING OBSERVATIONS OF THIS REGION
DIFFICULT. A NUMBER OF OTHER ACTIVE REGIONS PRODUCED SMALL FLARES,
INCLUDING 8773 (S12W71), 8778 (S14W33), AND 8781 (S13E22).
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE WITH A CHANCE OF A MAJOR FLARE FROM REGION 8771 BEFORE IT
COMPLETELY DEPARTS THE VISIBLE DISK.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET TO UNSETTLED. ACTIVITY LEVELS MAY BE
ENHANCED DURING THE 3-DAY FORECAST PERIOD DUE TO A PARTIAL-HALO CME
ON NOV 26 AND/OR A HIGH-SPEED CORONAL HOLE STREAM.
