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 250 Publicado el 2200Z a las 07 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z SOLAR ACTIVITY WAS LOW. THERE WERE TWO C-CLASS FLARES
WHICH WERE NOT OBSERVED OPTICALLY: A C1.7 AT 06/2112Z AND A C1.2 AT
07/1358Z. REGION 8690 (N13E60) HAS ROTATED MORE FULLY INTO VIEW AND
IS AN 80 MILLIONTHS D-TYPE GROUP. A NEW REGION 8691 EMERGED NEAR
S30W32 DURING THE PAST 24 HOURS. NEW REGIONS 8692 (S25E74) AND 8693
(N12E79) ROTATED INTO VIEW. BOTH OF THESE GROUPS SHOW SPOTS WITH
PENUMBRA.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO ACTIVE LEVELS. ACE
REAL-TIME SOLAR WIND MEASUREMENTS INDICATE THE ARRIVAL OF A
HIGH-SPEED, LOW DENSITY SOLAR WIND STREAM AT ABOUT 07/0900Z. THE
HIGH VELOCITY AND FREQUENTLY OSCILLATING BZ COMPONENT OF THE
MAGNETIC FIELD RESULTED IN AN INCREASE IN ACTIVITY TO UNSETTLED TO
ACTIVE LEVELS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED FOR THE NEXT THREE DAYS. THERE IS A
FAIR CHANCE FOR SOME ACTIVE PERIODS DURING THE NEXT 24 HOURS,
HOWEVER, IN RESPONSE TO THE HIGH SPEED SOLAR WIND STREAM.
