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 257 Publicado el 2200Z a las 14 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 13-2100Z hasta 14-2100Z SOLAR ACTIVITY WAS LOW. SEVERAL MINOR, MOSTLY OPTICALLY
UNCORRELATED C-CLASS X-RAY EVENTS OCCURRED THROUGHOUT THE PERIOD.
SMALL GROWTH WAS OBSERVED IN REGIONS 8690 (N15W34) AND 8699
(N21W11). NO SIGNIFICANT CHANGES WERE NOTED IN ANY OF THE REMAINING
FOUR SUNSPOT REGIONS. AN IMPRESSIVE PROMINENCE ERUPTION/CME ON THE
NW LIMB WAS OBSERVED FROM SPACE-BASED IMAGERY AT AROUND 14/0500UT.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
AT LOW LEVELS. REGIONS 8690, 8692 (S27W14), 8699 (N21W11), AND 8700
(N14E59), ALL HAVE POTENTIAL FOR C-CLASS X-RAY ACTIVITY AND A SMALL
CHANCE FOR AN M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 13-2100Z a 14-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MINOR STORMING. THIS
ONGOING DISTURBANCE, ASSOCIATED WITH A HIGH-SPEED CORONAL HOLE WIND
STREAM, CONTINUES TO PRODUCE PERIODS OF MINOR STORMING DURING LOCAL
NIGHTTIME HOURS,
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD WILL
CONTINUE AT QUIET TO ACTIVE LEVELS DURING LOCAL DAYLIGHT HOURS AND
UNSETTLED TO MINOR STORM DURING LOCAL NIGHTTIME. EFFECTS FROM THE
HIGH-SPEED CORONAL HOLE WIND STREAM WILL BEGIN TO DIMINISH TOMORROW;
HOWEVER, WE MAY EXPERIENCE ACTIVE TO MINOR STORM CONDITIONS ON DAY
TWO FROM CME'S OBSERVED DURING THE PAST TWO DAYS.
