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 090 Publicado el 2200Z a las 31 MAR 1998IA. Análisis de regiones solares activas y de actividad desde 30-2100Z hasta 31-2100Z SOLAR ACTIVITY WAS LOW. SEVERAL C-CLASS EVENTS OCCURRED
TODAY, THE LARGEST OF WHICH WAS A C2/SF AT 0302Z FROM REGION 8190
(S22E36). REGION 8190 HAS SHOWN STEADY GROWTH DURING THE PAST 24
HOURS AND WAS THE SOURCE OF THE MAJORITY OF TODAY'S FLARE ACTIVITY.
NEW REGION 8191 (S23E48) WAS ASSIGNED TODAY AND IS A SMALL BIPOLAR
GROUP JUST EAST OF 8190. REGION 8185 (S25W51) IS STILL THE LARGEST
REGION ON THE DISK BUT WAS DECLINING IN SUNSPOT AREA AND MAGNETIC
FIELD INTENSITY. LASCO IMAGES BEGINNING AT 31/0626Z SHOWED A LARGE
ERUPTION OF MATERIAL; THE PROJECTION WAS FROM THE SOUTHWESTERN PART
OF THE DISK. THE LACK OF ANY CORRESPONDING SIGNATURES ON THE DISK
SUGGEST THAT THE SOURCE WAS PROBABLY ON THE BACK SIDE OF THE SUN.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
THERE CONTINUES TO BE A SLIGHT CHANCE FOR ISOLATED M-CLASS EVENTS.
REGION 8190 IS EXPECTED TO BE THE MOST ACTIVE REGION OVER THE NEXT
THREE DAYS.
IIA. Resumen de la actividad geofísica 30-2100Z a 31-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET TO UNSETTLED. MINOR INTENSITY
SUBSTORMS WERE RECORDED AT HIGH LATITUDE BETWEEN FROM 0300-0900Z,
LEADING TO UNSETTLED LEVELS AT MID-LATITUDE STATIONS AND ACTIVE
LEVELS FOR THE PLANETARY INDICES. THE FIELD WAS QUIET AT ALL
LATITUDES FOR THE REMAINDER OF THE PERIOD. THE GREATER THAN 2 MEV
ELECTRON FLUXES ATTAINED HIGH LEVELS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE, WITH A CHANCE FOR SOME MINOR
STORM LEVEL CONDITIONS, OVER THE NEXT 24-48 HOURS. ENHANCED ACTIVITY
IS POSSIBLE BECAUSE OF A TRANSIENT ASSOCIATED WITH THE FILAMENT
ERUPTION ON 30 MARCH. CONDITIONS ARE EXPECTED TO RETURN TO UNSETTLED
TO QUIET LEVELS BY THE THIRD DAY.
