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 148 Publicado el 2200Z a las 28 MAY 1998IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8226 (N18W81)
PRODUCED A M1/SF WITH AN ERUPTIVE PROMINENCE AND MINOR RADIO BURSTS
AT 28/1353Z. THIS REGION IS ALSO RESPONSIBLE FOR SEVERAL C-CLASS
SUBFLARES INCLUDING A C8 AT 26/1912Z WHICH ALSO PRODUCED AN ERUPTIVE
PROMINENCE. LIMB PROXIMITY HAS MADE MEASUREMENTS DIFFICULT BUT
MAGNETIC ANALYSIS SUGGEST A BETA-GAMMA CONFIGURATION. REGION 8224
HAS ROTATED AROUND THE WEST LIMB NEAR S24 BUT DID PRODUCE A C3/SF AT
26/0101Z. REGION 8227 (N26E53), A D-TYPE BETA GROUP, PRODUCED A
C2/SF WITH MINOR RADIO BURSTS AT 28/1126Z.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8226 IS CAPABLE OF FURTHER M-CLASS ACTIVITY AS
IT ROTATES THE WEST LIMB. ISOLATED C-CLASS FLARES ARE POSSIBLE FROM
REGION 8227.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED THROUGH 30/1600Z. WE EXPECT
PERIODS OF ACTIVE TO MINOR STORM CONDITIONS ON 30-31 MAY IN RESPONSE
TO THE LONG DURATION C7 X-RAY EVENT ON 27/1335Z. A CME OCCURRED WITH
THIS EVENT AND EJECTA APPEARS EARTHBOUND.
