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 040 Publicado el 2200Z a las 09 FEB 1999IA. Análisis de regiones solares activas y de actividad desde 08-2100Z hasta 09-2100Z SOLAR ACTIVITY WAS LOW. THREE C-CLASS X-RAY BURSTS
OCCURRED, THE LARGEST, A C-2/SF AT 09/0508Z FROM REGION 8453
(S25W48). A TYPE II SWEEP ALSO OCCURRED WITH THIS FLARE. THE
REMAINING TWO C-1 X-RAY BURSTS WERE OPTICALLY UNCORRELATED. LIMB
PROXIMITY STILL PROHIBITS ACCURATE ANALYSIS OF REGION 8458 (S22E65),
A LARGE SPOT GROUP ROTATING AROUND THE SE LIMB; HOWEVER, NO
SIGNIFICANT ACTIVITY HAS BEEN OBSERVED YET DURING ITS LIMB CROSSING.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
ISOLATED C-CLASS FLARES ARE POSSIBLE FROM REGION 8456 AND 8458.
IIA. Resumen de la actividad geofísica 08-2100Z a 09-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH ISOLATED ACTIVE CONDITIONS
OVER THE NEXT TWO DAYS. ACTIVITY WILL DECLINE TO QUIET TO UNSETTLED
NEAR THE END OF THE PERIOD. THE GREATER THAN 2 MEV ELECTRON FLUX AT
GEO-SYNCHRONOUS ALTITUDE IS EXPECTED TO BE AT MODERATE TO HIGH
LEVELS.
