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 346 Publicado el 2200Z a las 12 DEC 1999IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z SOLAR ACTIVITY WAS LOW. ONLY ONE MINOR C-CLASS EVENT
WAS OBSERVED DURING THE PERIOD. MOST OF THE REGIONS ARE CURRENTLY
STABLE OR SHOWING SIGNS OF DECAY. NO NEW REGIONS WERE NUMBERED
TODAY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. SOLAR WIND DATA INDICATED
A SIGNIFICANT INCREASE IN VELOCITY AND TEMPERATURE STARTING AROUND
12/1630Z. ACTIVE CONDITIONS WERE IMMEDIATELY OBSERVED AFTERWARDS.
THE GREATER THAN 2 MEV ELECTRONS AT GEOSYNCHRONOUS ORBIT WERE AT
HIGH LEVELS DURING THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTELY QUIET TO ACTIVE ON THE FIRST DAY AS
THE CURRENT DISTURBANCE SUBSIDES. QUIET TO UNSETTLED CONDITIONS ARE
EXPECTED DURING THE REMAINDER OF THE PERIOD.
