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 205 Publicado el 2200Z a las 24 JUL 1998IA. Análisis de regiones solares activas y de actividad desde 23-2100Z hasta 24-2100Z SOLAR ACTIVITY REMAINED AT LOW LEVELS. ISOLATED C-CLASS
SUBFLARES OCCURRED, THE LARGEST OF WHICH WAS A C8/SF FROM REGION
8280 (S23E40) AT 24/0338UT. REGION 8280 REMAINED THE LARGEST GROUP
ON THE DISK AND RETAINED A SIMPLE BIPOLAR MAGNETIC STRUCTURE. REGION
8282 (N32E43) GREW AT A MODERATE PACE AND PRODUCED ISOLATED
SUBFLARES. NO NEW REGIONS WERE NUMBERED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
PREDOMINATELY LOW WITH A FAIR CHANCE FOR AN ISOLATED M-CLASS FLARE
FROM EITHER REGION 8280 OR 8282.
IIA. Resumen de la actividad geofísica 23-2100Z a 24-2100Z
THE GEOMAGNETIC FIELD WAS AT UNSETTLED TO MINOR STORM LEVELS WITH
ISOLATED MAJOR STORM PERIODS OBSERVED AT HIGH LATITUDES. ACE
NEAR-REAL-TIME SOLAR WIND DATA INDICATED THE ACTIVITY WAS DUE TO A
HIGH SPEED STREAM ASSOCIATED WITH AN EXTENSION OF THE NORTHERN POLAR
CORONAL HOLE. THE GREATER THAN 2 MEV ELECTRON FLUX REACHED HIGH
LEVELS AT 23/2240UT, THEN VARIED FROM MODERATE TO HIGH LEVELS FOR
THE REST OF THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE CORONAL HOLE-RELATED
DISTURBANCE IS EXPECTED TO SUBSIDE TO QUIET TO ACTIVE LEVELS
TOMORROW. QUIET TO UNSETTLED CONDITIONS ARE EXPECTED FOR THE
REMAINDER OF THE PERIOD. THE GREATER THAN 2 MEV ELECTRON FLUX IS
EXPECTED TO REMAIN AT MODERATE TO HIGH LEVELS FOR MOST OF THE
PERIOD.
