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 254 Publicado el 2200Z a las 11 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z SOLAR ACTIVITY INCREASED TO LOW LEVELS BY VIRTUE OF AN
OPTICALLY UNCORRELATED C1 X-RAY FLARE AT 11/0631Z. ISOLATED B-CLASS
X-RAY FLARES WERE ALSO DETECTED, ONE OF WHICH WAS ASSOCIATED WITH A
SUBFLARE IN REGION 8690 (N14E06). REGION 8690 DISPLAYED A SMALL
INCREASE IN SPOT COUNT DURING THE PERIOD, BUT WAS OTHERWISE
UNREMARKABLE. NEW REGIONS 8696 (N14W48), 8697 (S20W06), 8698
(S16E64), AND 8699 (N21E29) WERE ASSIGNED TODAY. REGION 8699
APPEARED TO BE GROWING AT A MODERATE PACE AND PRODUCED A SMALL
SUBFLARE LATE IN THE PERIOD.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
AT LOW LEVELS. REGIONS 8690, 8692, AND 8699 MAY PRODUCE C-CLASS
FLARES.
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
GEOMAGNETIC FIELD ACTIVITY RANGED FROM QUIET TO ACTIVE LEVELS.
UNSETTLED TO ACTIVE LEVELS OCCURRED DURING 11/0100 - 0500Z FOLLOWING
A SOUTHWARD TURNING OF THE BZ COMPONENT OF THE INTERPLANETARY
MAGNETIC FIELD. FIELD ACTIVITY DECLINED TO MOSTLY QUIET LEVELS AFTER
11/0500Z.
IIB. Pronóstico de la actividad geofísica
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO VARY FROM QUIET TO ACTIVE LEVELS. INTERMITTENT ACTIVE
PERIODS ARE EXPECTED IN RESPONSE TO RECURRENT CORONAL HOLE EFFECTS.
