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 199 Publicado el 2200Z a las 18 JUL 1999IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY WAS LOW. THE MOST ACTIVE REGION WAS 8636
(N20E60). THIS REGION PRODUCED SEVERAL C-CLASS X-RAY EVENTS AS WELL
AS SEVERAL OPTICAL SUBFLARES. OPTICAL OBSERVATORIES REPORT NEAR
CONTINUOUS PLAGE FLUCTUATIONS AND POINT BRIGHTENING IN REGION 8636.
IT CURRENTLY HAS AN ESO, BETA-GAMMA SPOT CLASSIFICATION WITH 10
SPOTS. THE REST OF THE DISK AND LIMBS WERE MOSTLY QUIET AND STABLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8636 IS CAPABLE OF PRODUCING ISOLATED M-CLASS
EVENTS AT ANY TIME.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET WITH POSSIBLE UNSETTLED CONDITIONS ON
THE SECOND DAY OF THE FORECAST PERIOD.
