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 241 Publicado el 2200Z a las 29 AUG 1998IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z SOLAR ACTIVITY WAS LOW. SEVERAL C-CLASS EVENTS WERE
OBSERVED DURING THE LAST 24 HOURS. THE LARGEST OF THESE WAS A C5 AT
1836Z WHICH WAS NOT OBSERVED OPTICALLY. REGION 8307 (N32W52)
CONTRIBUTED AT LEAST ONE OF THE C-CLASS EVENTS AT 1535Z. THE GROUP
WAS ESSENTIALLY UNCHANGED AND STABLE OVER THE PAST 24 HOURS. REGION
8319 (N19W29) PRODUCED A FEW SUBFLARES DURING THE PERIOD AND
CONTINUES TO INCREASE IN SIZE. REGION 8323 (S23E65) ROTATED FURTHER
INTO VIEW TODAY AND APPEARS TO BE A BIPOLAR GROUP WITH PENUMBRA IN
THE LEADER AND TRAILER.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
PREDOMINANTLY LOW. HOWEVER, EACH OF THE REGIONS 8307, 8319 AND 8323
HAS THE POTENTIAL FOR AN M-CLASS EVENT, SO THERE IS A SLIGHT CHANCE
FOR MODERATE LEVELS DURING THE NEXT THREE DAYS.
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY UNSETTLED TO ACTIVE. THERE WERE SOME
ISOLATED MINOR STORM PERIODS AT THE HIGH LATITUDES. ACE REAL-TIME
SOLAR WIND DATA CONTINUE TO SHOW A LOW DENSITY, HIGH SPEED STREAM
WITH WAVE-LIKE ACTIVITY IN THE BZ INTERPLANETARY FIELD. VARIATIONS
IN BZ DOWN TO -5 NT ARE UNDOUBTEDLY THE SOURCE OF THE ENHANCED
MAGNETIC ACTIVITY. THE GREATER THAN 2 MEV ELECTRON FLUXES HAVE BEEN
HIGH. THE GREATER THAN 10 MEV PROTON EVENT THAT BEGAN 24/2355Z ENDED
TODAY AT 29/1210Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT TWO DAYS, DECLINING
TO UNSETTLED TO SLIGHTLY ACTIVE BY THE THIRD DAY.
