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 037 Publicado el 2200Z a las 06 FEB 1999IA. Análisis de regiones solares activas y de actividad desde 05-2100Z hasta 06-2100Z SOLAR ACTIVITY REMAINED AT VERY LOW LEVELS WITH
ISOLATED B-CLASS X-RAY FLARES, NONE OF WHICH WERE OPTICALLY
CORRELATED. THERE WERE TWO SPOTTED REGIONS ON THE DISK, INCLUDING
NEWLY NUMBERED REGION 8455 (S19E33). BOTH REGIONS WERE SMALL,
STRUCTURALLY SIMPLE, AND STABLE. A 23-DEGREE FILAMENT, LAST SEEN
CENTERED NEAR S54W34, DISAPPEARED DURING 06/1219 - 1540Z. TODAY'S
10.7 CM RADIO FLUX READING WAS THE LOWEST SINCE LAST JULY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
AT VERY LOW LEVELS DURING THE FIRST DAY OF THE FORECAST PERIOD. AN
INCREASE IN ACTIVITY LEVELS IS POSSIBLE DURING THE REMAINING DAYS
WITH THE EXPECTED RETURN OF OLD REGIONS 8439 (S23, L = 272) AND 8440
(N19, L = 265).
IIA. Resumen de la actividad geofísica 05-2100Z a 06-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS FOR MOST OF
THE PERIOD. HOWEVER, ACTIVE LEVELS WERE DETECTED AT MIDDLE LATITUDES
DURING 06/0500 - 0600Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT QUIET TO UNSETTLED LEVELS DURING THE FIRST TWO
DAYS. ACTIVE LEVELS ARE POSSIBLE BEGINNING 09 FEBRUARY IN RESPONSE
TO RECENT FILAMENT DISAPPEARANCES.
