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 109 Publicado el 2200Z a las 19 APR 1999IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z SOLAR ACTIVITY REMAINED AT VERY LOW LEVELS. MINOR
GROWTH OCCURRED IN REGIONS 8517 (N22W63) AND 8518 (S14E40), BOTH OF
WHICH PRODUCED ISOLATED SUBFLARES. THE REMAINING REGIONS WERE EITHER
STABLE OR DECLINING. NEW REGIONS 8520 (N20E12) AND 8521 (N34W07)
WERE NUMBERED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGIONS 8517 AND 8518 MAY PRODUCE C-CLASS FLARES.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
GEOMAGNETIC FIELD ACTIVITY RANGED FROM QUIET TO ACTIVE LEVELS DURING
THE PERIOD. ACTIVE LEVELS WERE DETECTED AT ALL LATITUDES DURING
19/0900 - 1000Z. QUIET TO UNSETTLED LEVELS OCCURRED DURING THE
REMAINING HOURS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT UNSETTLED TO MINOR STORM LEVELS DURING THE FIRST
TWO DAYS IN RESPONSE TO A PARTIAL-HALO CME OBSERVED ON 17 APRIL.
FIELD ACTIVITY IS EXPECTED TO DECLINE TO QUIET TO UNSETTLED LEVELS
ON THE FINAL DAY.
