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 049 Publicado el 2200Z a las 18 FEB 2000IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY WAS LOW. ONLY FOUR LOW INTENSITY C-CLASS
EVENTS WERE OBSERVED TODAY. THE LARGEST WAS AN UNCORRELATED C2 AND
REGION 8869 (S21W35) PRODUCED A C1/SF WITH A HIGH SPEED (1400 KM/S)
RADIO SWEEP AT 18/0844UT. REGION 8872, WHICH PRODUCED AN M1/2N FLARE
WITH A FULL-HALO CME YESTERDAY, BECAME SPOTLESS TODAY. THE REST OF
THE DISK AND LIMBS WERE MOSTLY QUIET AND STABLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MOSTLY LOW WITH A REMOTE CHANCE OF AN ISOLATED M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. THE GREATER THAN 10 MEV PROTONS AT
GEOSYNCHRONOUS ORBIT WERE AT HIGH LEVELS FROM 18/1130 TO 18/1405UT.
AFTER THAT TIME THEY REMAINED AT MODERATE LEVELS FOR THE REST OF THE
PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE FIRST DAY OF THE PERIOD.
THE SECOND AND THIRD DAYS OF THE PERIOD ARE EXPECTED TO SEE ACTIVE
TO MINOR STORM LEVELS WITH POSSIBLE MAJOR STORMING AT HIGHER
LATITUDES. THIS WILL BE THE RESULT OF THE SHOCK FROM A FULL-HALO CME
PRODUCED BY THE M2/2N EVENT ON FEBRUARY 17TH.
