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 332 Publicado el 2200Z a las 28 NOV 1998IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z SOLAR ACTIVITY BECAME HIGH. REGION 8395 (N20E33)
PRODUCED A X3/3N AT 28/0552Z. THIS EVENT HAD TYPE II/IV SWEEPS AND
MODERATE CENTIMETRIC RADIO BURST INCLUDING 3600 SFU'S AT 2695 MHZ. A
PARTIAL-HALO CME WAS ALSO ASSOCIATED WITH THIS FLARE. OBSERVATORIES
REPORTED SOME SPOT GROWTH PRIOR TO THE FLARE. REGION 8395 IS NOW A
MODERATELY COMPLEX F-TYPE GROUP WITH A BETA-GAMMA MAGNETIC
CONFIGURATION. IT PRODUCED A FEW SUBFLARES SHORTLY AFTER THE X3/3N,
BUT HAS BEEN MOSTLY STABLE SINCE 28/1400Z. REGION 8393 (S18E12)
DISPLAYED A BIT OF MAGNETIC COMPLEXITY, BUT WAS STABLE DURING THE
PERIOD. THE REMAINING REGIONS WERE STABLE. NO NEW REGIONS WERE
NUMBERED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE. REGION 8395 HAS MAINTAINED A LARGE FIELD OF NEAR FLARE
INTENSITY PLAGE SINCE THE X-FLARE TODAY. FREQUENT SUBFLARES,
FLUCTUATIONS, AND SURGES ALSO SUGGEST THE POSSIBILITY OF ANOTHER
MAJOR FLARE. REGION 8393 MAY PRODUCE C-CLASS ACTIVITY WITH A SMALL
CHANCE OF AN M-CLASS FLARE.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET THROUGH DAY 1. A MINOR DISTURBANCE FROM THE
M1/2N FLARE EARLY ON THE 27TH MAY CAUSE ACTIVE CONDITIONS ON DAY 2
AND 3.
