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
:::::::::: CORRECTED COPY :::::::::: SDF Número 147 Publicado el 2200Z a las 27 MAY 1998IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z SOLAR ACTIVITY WAS LOW. REGIONS 8224 (S24W90) AND 8226
(N18W66) PRODUCED SEVERAL C-CLASS FLARES INCLUDING A C7 LONG
DURATION EVENT AT 27/1335Z WITH MODERATE RADIO BURSTS. BOTH REGIONS
HAD A FLARE IN PROGRESS DURING THE X-RAY EVENT. LASCO IMAGERY
SHOWS A LARGE CORONAL MASS EJECTION ORIGINATING FROM THE NW. WELL
DEFINED POST FLARE LOOPS ARE OBVIOUS ON THE EIT IMAGES SUGGESTING
THAT REGION 8226 WAS THE PROBABLE SOURCE FOR THE LONG DURATION
EVENT. A MODERATE 8 FREQUENCY RADIO BURST AND TENFLARE ALSO
OCCURRED WITH THIS EVENT. REGION 8224 WAS SPOTLESS FOR MOST OF ITS
TRANSIT ON THE VISIBLE DISK BEFORE DEVELOPING RAPIDLY EARLY
YESTERDAY. SPOTS ARE NOW VISIBLE IN THIS REGION AS IT ROUNDS THE
WEST LIMB. REMAINING REGIONS HAVE BEEN QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. DRAMATIC GROWTH IN REGION 8224 WILL LIKELY ENSURE
CONTINUED C-CLASS ACTIVITY AND A DEVELOPING CHANCE FOR M-CLASS.
REGION 8226 WILL ALSO CONTINUE PRODUCING C-CLASS WITH A CHANCE OF
A M-CLASS FLARE.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN MOSTLY QUIET TO UNSETTLED. WE ARE EXPECTING MINOR
GEOEFFECTIVNESS ON DAY 3 FROM TODAY'S LONG DURATION EVENT.
