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 263 Publicado el 2200Z a las 20 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z SOLAR ACTIVITY WAS LOW. REGION 8699 (N24W88) PRODUCED
THE LARGEST FLARE, A C9/1F AT 19/2312UT. REGION 8700 (N12W19) ALSO
PRODUCED SMALL C-CLASS FLARES. REGION 8700 CONTINUES TO SLOWLY
DECAY. REMAINING DISK REGIONS ARE SMALL AND SIMPLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. C-CLASS ACTIVITY IS EXPECTED TO CONTINUE, PRIMARILY IN
REGION 8700. THE LIKELIHOOD OF M-CLASS ACTIVITY IS DIMINISHING WITH
THE DEPARTURE OF REGION 8699 AND THE DECAY IN REGION 8700.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX WAS MODERATE TO HIGH.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED. A SOLAR WIND SIGNATURE FROM THE
SEP 16 CME/DSF EVENT HAS NOT YET BEEN SEEN AND ITS ARRIVAL IS
BECOMING LESS LIKELY.
