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 359 Publicado el 2200Z a las 25 DEC 1998IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8421 (N28E53)
PRODUCED SEVERAL C-CLASS EVENTS DURING THE PERIOD AND A M1/SF AT
25/0634Z. THERE WERE TWO OPTICALLY UNCORRELATED EVENTS, A C2 AT
25/0414Z AND A C1 AT 25/2020Z.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE THROUGH THE PERIOD. REGION 8421 REMAINS CAPABLE OF
PRODUCING OCCASIONAL M-CLASS EVENTS.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE FIELD WAS EFFECTED
SLIGHTLY BY A TRANSIENT SIGNATURE FROM AN UNKNOWN SOURCE. THIS WAS
REFLECTED IN THE SOLAR WIND DATA (SPEED INCREASED WHILE DENSITY
DECREASED) AT 25/0535Z RECEIVED FROM THE ACE SPACECRAFT.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO SLIGHTLY UNSETTLED FOR THE FORECAST PERIOD.
