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 114 Publicado el 2200Z a las 24 APR 1998

IA. Análisis de regiones solares activas y de actividad desde 23-2100Z hasta 24-2100Z

SOLAR ACTIVITY WAS LOW. AN UNCORRELATED C8 X-RAY BURST WAS DETECTED AT 24/0852Z. THIS MAY HAVE BEEN ASSOCIATED WITH AN ERUPTIVE PROMINENCE ON THE SE LIMB AT S34 WHICH BEGAN AT 24/0450Z. THIS EPL ENDED AT 24/0940Z. THE REMAINDER OF THE VISIBLE DISK WAS QUIET. NEW REGION 8210 (S19E70) WAS NUMBERED TODAY. THIS REGION WAS THE SITE OF YESTERDAY'S CME ASSOCIATED WITH AN X1 FLARE, A LOOP PROMINENCE SYSTEM AND NUMEROUS POINT BRIGHTENINGS. THE REGION CONTAINS ONLY BRIGHT PLAGE AND ACTIVE SURGING AT THIS TIME, BUT PRELIMINARY REPORTS OF SPOTS WERE RECEIVED LATE IN THE PERIOD.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE AS REGION 8210 ROTATES ONTO THE VISIBLE DISK. THIS REGION IS EXPECTED TO PRODUCE C-CLASS AND M-CLASS ACTIVITY DURING ITS TRANSIT OF THE DISK, AS WELL AS ISOLATED X-CLASS ACTIVITY.
IIA. Resumen de la actividad geofísica 23-2100Z a 24-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO MINOR STORM. ACTIVE TO MINOR STORM CONDITIONS SET IN ABOUT 23/1900Z WITH THE ARRIVAL OF A SHOCK RESULTING FROM THE CME REPORTED ON 21 APRIL. THIS ACTIVITY LASTED UNTIL 24/1500Z WHEN THE FIELD FINALLY SETTLED DOWN. THE GREATER THAN 10 MEV PROTON EVENT ENDED AT 24/1550Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT 18 HOURS, THEN QUIET TO UNSETTLED FOR THE REMAINDER OF THE FORECAST PERIOD. HIGH LATITUDE STATIONS MAY STILL EXPERIENCE ISOLATED PERIODS OF ACTIVE TO MINOR STORM CONDITIONS FOR THE NEXT 18 HOURS.
