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 356 Publicado el 2200Z a las 22 DEC 1998IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z SOLAR ACTIVITY WAS LOW. REGION 8416 (N19E46) PRODUCED A
C1/SF AT 22/1833Z. THIS REGION EXHIBITED SLOW DECAY DURING THE
PERIOD. REGION 8415 (N20E12) PRODUCED SMALL SUBFLARES AND CONTINUED
TO SLOWLY DECAY AND SIMPLIFY. THE FILAMENT IN REGION 8414 (N26W23)
GREW SUBSTANTIALLY DURING THE PERIOD AND AT TIMES SHOWED STRONG
MOTION. RECENT X-RAY IMAGERY SHOWS A LARGE ENHANCED AREA OVER THE
NORTHEAST LIMB WHERE SEVERAL REGIONS ARE DUE TO RETURN.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD BE PREDOMINANTLY
LOW DURING THE NEXT THREE DAYS. REGION 8415 RETAINS THE CAPABILITY
OF PRODUCING AN ISOLATED M-CLASS EVENT. THE REGIONS RETURNING TO THE
EAST LIMB COULD INCREASE THE FREQUENCY OF C-CLASS EVENTS. BETTER
ASSESSMENT OF THEIR FLARE POTENTIAL MUST AWAIT THEIR APPEARANCE ONTO
THE VISIBLE DISK. THE FILAMENT IN REGION 8414 IS EXPECTED TO ERUPT
SOMETIME PRIOR TO WEST LIMB TRANSIT. IF IT DOES, A LONG DURATION
X-RAY EVENT AND LARGE CORONAL MASS EJECTION WOULD LIKELY OCCUR.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. THE DISTURBANCE FROM THE HALO
CORONAL MASS EJECTION ON 18 DEC FAILED TO MATERIALIZE.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD SHOULD BE
QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT THREE DAYS.
