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 252 Publicado el 2200Z a las 09 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 08-2100Z hasta 09-2100Z SOLAR ACTIVITY DECREASED TO LOW LEVELS. REGION 8690
(N13E33) PRODUCED THE SOLE C-CLASS FLARE OF THE PERIOD, A
LONG-DURATION C3/SF AT 09/1637Z ACCOMPANIED BY A 150 SFU TENFLARE
AND A 12 DEGREE FILAMENT DISAPPEARANCE. NO SIGNIFICANT CHANGES WERE
OBSERVED IN ANY OF THE VISIBLE REGIONS DURING THE PERIOD.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
AT LOW LEVELS THROUGHOUT THE PERIOD.
IIA. Resumen de la actividad geofísica 08-2100Z a 09-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS. A WEAK SUDDEN
IMPULSE (05 NT, AS MEASURED BY THE BOULDER USGS MAGNETOMETER)
OCCURRED AT 09/1257Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN AT QUIET TO UNSETTLED LEVELS DURING THE FIRST
HALF OF THE PERIOD. AN INCREASE TO UNSETTLED TO ACTIVE LEVELS IS
EXPECTED TO OCCUR DURING THE SECOND HALF OF THE PERIOD DUE TO
RECURRENT CORONAL HOLE EFFECTS.
