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 038 Publicado el 2200Z a las 07 FEB 1999IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z SOLAR ACTIVITY REMAINED AT VERY LOW LEVELS. ISOLATED
B-CLASS X-RAY FLARES OCCURRED INCLUDING A SMALL OPTICAL FLARE FROM A
SPOTLESS PLAGE REGION NEAR N21E15. ALL SPOT GROUPS WERE SMALL,
QUIET, AND STABLE INCLUDING NEWLY NUMBERED REGION 8456 (N23E65).
IB. Pronóstico de la actividad solar
A GRADUAL INCREASE TO LOW LEVELS IS
EXPECTED DURING THE PERIOD WITH THE EXPECTED RETURN OF OLD REGIONS
8439 (S23, L = 272) AND 8440 (N19, L = 265).
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS DURING MOST OF
THE PERIOD. HOWEVER, ACTIVE LEVELS WERE DETECTED AT SOME MIDDLE AND
HIGH LATITUDE STATIONS DURING 07/0500 - 0600Z, 07/1000 - 1200Z, AND
07/1400 - 1500Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN AT MOSTLY QUIET TO UNSETTLED LEVELS ON THE FIRST
DAY. AN INCREASE TO UNSETTLED TO ACTIVE LEVELS IS EXPECTED DURING 09
FEBRUARY IN RESPONSE TO RECENT FILAMENT DISAPPEARANCES. ACTIVE
LEVELS ARE ALSO POSSIBLE ON 10 FEBRUARY DUE TO CORONAL HOLE EFFECTS.
THE GT 2 MEV ELECTRON FLUX AT GEO-SYNCHRONOUS ALTITUDE MAY REACH
HIGH LEVELS DURING THE LATTER HALF OF THE FORECAST PERIOD.
