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 256 Publicado el 2200Z a las 13 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 12-2100Z hasta 13-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT THIS PERIOD
WAS A C4/SF FROM REGION 8699 (N21E01), WHICH OCCURRED AT 13/0846UT.
THE RAPID GROWTH NOTED IN THIS REGION OVER THE PAST 48 HOURS
SUBSIDED DURING THE LATTER HALF OF THIS PERIOD. THE REGION RETAINS A
MODERATELY COMPLEX MAGNETIC STRUCTURE BUT HAS RELATIVELY SMALL WHITE
LIGHT AERIAL COVERAGE. REGION 8690 (N14W06) EXHIBITED GROWTH,
PRODUCED OCCASIONAL SUBFLARES LATE IN THE PERIOD AND WAS THE LIKELY
SOURCE FOR A TYPE II SWEEP AT 13/1622UT. NEW REGION 8701 (N18E13),
WAS NUMBERED TODAY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
SEVERAL EXISTING REGIONS HAVE C-CLASS FLARE POTENTIAL WITH A SMALL
CHANCE OF AN ISOLATED M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 12-2100Z a 13-2100Z
THE GEOMAGNETIC FIELD WAS AT UNSETTLED TO MINOR STORM CONDITIONS WITH
AN ISOLATED MAJOR STORM PERIOD OBSERVED BETWEEN 13/0000 - 0300Z.
THIS DISTURBANCE IS LIKELY ASSOCIATED WITH A HIGH-SPEED CORONAL HOLE
WIND STREAM.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO CONTINUE AT UNSETTLED TO MINOR STORM LEVELS WITH THE
MOST DISTURBED CONDITIONS EXPECTED DURING LOCAL NIGHTTIME HOURS.
