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 361 Publicado el 2200Z a las 27 DEC 1999IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8806 (N20W53)
PRODUCED TWO SMALL M FLARES, AN M1/SF AT 27/0146UT AND AN M2/SN AT
27/1154UT. THIS MAGNETICALLY COMPLEX REGION IS SLOWLY DECLINING AS
IT APPROACHES WEST LIMB. ONLY MINOR ACTIVITY WAS OBSERVED FROM THE
REMAINING THREE SPOTTED REGIONS. THE PROMINENCE ON THE EAST LIMB
NEAR N40 IS IN THE PROCESS OF ERUPTING. SOLAR X-RAY AND RADIO
BACKGROUND FLUX ARE DROPPING.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. THERE IS A CHANCE FOR MAJOR FLARES UNTIL AFTER REGION
8806 ROTATES OFF THE DISK ON 31 DEC.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED. A SHOCK WAS
OBSERVED AT THE ACE SPACECRAFT AT 26/2126UT RESULTING IN A MINOR
INCREASE IN ACTIVITY AT THE EARTH AFTER 26/2230UT.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET.
