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 221 Publicado el 2200Z a las 09 AUG 1999IA. Análisis de regiones solares activas y de actividad desde 08-2100Z hasta 09-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT OF THE PERIOD
WAS A C4/1F LONG DURATION EVENT FROM REGION 8657 (S30W22) AT
09/0258Z. A FAINT HALO CORONAL MASS EJECTION WAS OBSERVED WITH THIS
EVENT. REGION 8662 (S16E21), THE LARGEST REGION ON THE VISIBLE DISK,
DOUBLED IN SIZE, NOW AN E-TYPE REGION MEASURING OVER 230 MILLIONTHS
OF WHITE LIGHT AREA. FREQUENT FLUCTUATIONS AND MINOR SUBFLARES WERE
OBSERVED IN THIS REGION. THE PERIOD ENDED WITH AN OPTICALLY
UNCORRELATED LONG DURATION C2 X-RAY ENHANCEMENT. REMAINING REGIONS
WERE QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
AT LOW LEVELS. REGIONS 8657 AND 8662 WILL LIKELY CONTINUE TO PRODUCE
OCCASIONAL C-CLASS FLARES.
IIA. Resumen de la actividad geofísica 08-2100Z a 09-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. AN EXTENDED PERIOD OF
PREDOMINANTLY SOUTHWARD BZ DOMINATED MOST OF THE PERIOD, CAUSING
ACTIVE CONDITIONS DURING LOCAL NIGHTTIME HOURS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
