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 177 Publicado el 2200Z a las 26 JUN 1998

IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z

SOLAR ACTIVITY WAS LOW. A C6/SF AT 25/2107Z FROM REGION 8253 (N17E26) WAS THE HIGHLIGHT OF AN OTHERWISE QUIET DAY. TWO NEW REGIONS WERE NUMBERED, 8257 (N29W19) AND 8258 (S14E64), MAKING A TOTAL OF SIX SPOTTED REGIONS ON THE DISK.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
THE GEOMAGNETIC FIELD WAS AT MAJOR TO SEVERE STORM LEVELS DURING THE PAST 24 HOURS. A CORONAL MASS EJECTION WAS SEEN TO PASS THE ACE SPACECRAFT BEGINNING AT APPROXIMATELY 25/1600Z. THE LATTER HALF OF THE EVENT EXHIBITED STRONG, PROLONGED, SOUTHWARD MAGNETIC FIELDS FROM 25/2200Z TO 26/0600Z. THE SOLAR SOURCE OF THIS EJECTA IS LIKELY EITHER FROM ACTIVITY OCCURRING ON JUNE 20, OR JUNE 22. THE DISTURBANCE WEAKENEND DURING THE SECOND HALF OF THE PERIOD, GIVING WAY TO QUIET TO UNSETTLED CONDITIONS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS EXPECTED TO BE PRIMARILY UNSETTLED, WITH PERIODS OF ACTIVE CONDITIONS POSSIBLE DURING LOCAL NIGHTTIMES, FOR THE NEXT 24 HOURS. QUIET TO UNSETTLED CONDITIONS SHOULD PREVAIL BY THE END OF THE INTERVAL.
