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 202 Publicado el 2200Z a las 21 JUL 1999IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY WAS LOW. SEVERAL MINOR C-CLASS X-RAY
EVENTS WERE OBSERVED OVER THE PAST 24 HOURS. REGION 8639 (N38W38)
EXHIBITED SIGNIFICANT GROWTH, AND IS NOW A CLASS D SUNSPOT GROUP
WITH APPROXIMATELY 15 SPOTS. REGION 8636 (N21E25) EXHIBITED SLIGHT
GROWTH DURING THE PERIOD AND HAS MAINTAINED A BETA GAMMA MAGNETIC
CONFIGURATION WITH 35 SPOTS . REGION 8641 (N30W73), AND REGION 8642
(S18E66) WERE NUMBERED TODAY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8636 REMAINS CAPABLE OF PRODUCING C-CLASS AND
ISOLATED M-CLASS EVENTS.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. ACTIVE CONDITIONS WERE
OBSERVED DURING THE 21/1500-1800Z PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINATELY QUIET TO UNSETTLED WITH PERIODS OF
ACTIVE CONDITIONS DURING THE FIRST DAY OF THE PERIOD. THE UNSETTLED
TO ISOLATED ACTIVE CONDITIONS MAY BE THE RESULT OF A CME EARLY ON
THE 19TH. EXPECT QUIET TO UNSETTLED CONDITIONS DURING DAY TWO AND
THREE.
