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 021 Publicado el 2200Z a las 21 JAN 1998IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY BECAME VERY LOW. ONLY SMALL TO MID
B-CLASS FLARES WERE OBSERVED. A MODERATELY LARGE FILAMENT LOCATED
NEAR S57E19 FADED BETWEEN 21/0400-0603Z. THIS EVENT WAS ACCOMPANIED
BY A LONG DURATION ARCADE IN THE EUV AND A PARTIAL HALO CORONAL MASS
EJECTION. MOST OF THE HALO OF MATERIAL WAS VISIBLE AROUND THE SOUTH
POLE BUT SOME WAS SEEN INTO NORTHERN LATITUDES AND PRESUMABLY INTO
AND ABOVE THE ECLIPTIC PLANE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD CONTINUE AT A
VERY LOW LEVEL FOR THE NEXT THREE DAYS.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED. BRIEF
ACTIVE CONDITIONS WERE OBSERVED FROM 21/0600-0900Z. NEAR THE END OF
THE REPORTING PERIOD, SOLAR WIND VELOCITIES DROPPED FROM
APPROXIMATELY 450 KM/S TO NEAR 350 KM/S.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD SHOULD BE
QUIET TO UNSETTLED FOR 22-23 JAN. UNSETTLED TO ACTIVE CONDITIONS ARE
EXPECTED EARLY ON 24 JAN IN RESPONSE TO THE HALO CME MENTIONED
ABOVE. BRIEF MINOR STORM PERIODS ARE POSSIBLE ON THAT DAY.
