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 043 Publicado el 2200Z a las 12 FEB 2000IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8858 (N25W38)
PRODUCED AN M1/1N FLARE AT 0410Z. THE EVENT INCLUDED TYPE II AND IV
SWEEP, AS WELL AS MODERATE (340 SFU AT 245 MHZ) DISCRETE RADIO
BURSTS ACROSS THE SPECTRUM. THAT EVENT WAS THE HIGHLIGHT OF AN
OTHERWISE QUIET DAY. THE ELEVEN SPOTTED REGIONS COULD BE DESCRIBED
AS GENERALLY BEING IN A STATE OF DECAY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
THE GEOMAGNETIC FIELD VARIED FROM UNSETTLED TO SEVERE STORM LEVELS.
BOULDER MEASURED A SUDDEN COMMENCEMENT OF 19 NT AT 11/2353Z. MINOR
TO SEVERE STORM CONDITIONS FOLLOWED OVER THE NEXT 15 HOURS. THIS
ACTIVITY IS THOUGHT TO BE THE RESULT OF THE PASSAGE OF A CME THAT
LEFT THE SUN ON 09 FEBRUARY. THE GREATER THAN 10 MEV PROTON FLUX AT
GEOSYNCHRONOUS ORBIT WAS SLIGHTLY ENHANCED, STARTING AROUND 0600Z.
THE PEAK VALUE WAS 2 PFU AT 1120Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT MINOR STORM LEVELS THE NEXT 24 HOURS, AS EFFECTS
FROM TODAY'S STORM LINGER. THE SOLAR WIND SPEED IS STILL NEAR 550
KM/S. ACTIVITY SHOULD DIMINISH BY 14 FEBRUARY, FINALLY YIELDING TO
UNSETTLED LEVELS BY THE END OF THE PERIOD. NIGHTTIME SUBSTORMS ARE
EXPECTED FOR THE NEXT 48 HOURS.
