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 331 Publicado el 2200Z a las 27 NOV 1997IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z SOLAR ACTIVITY WAS HIGH. REGION 8113 (N20E60) PRODUCED
AN X2/2B FLARE AT 27/1317Z. THIS FLARE WAS ASSOCIATED WITH A 350 SFU
RADIO BURST AT 2695 MHZ AND A TYPE II SWEEP. THIS REGION APPEARS TO
BE A MODERATE-SIZED COMPLEX E-TYPE SUNSPOT GROUP, ALTHOUGH LIMB
PROXIMITY STILL INHIBITS COMPLETE ANALYSIS. THIS REGION ALSO
GENERATED SEVERAL SMALL C-CLASS FLARES SINCE YESTERDAY. OTHER
REGIONS WERE QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE TO HIGH WITH REGION 8113 AS THE PRIMARY FLARE PRODUCER.
ANOTHER MAJOR FLARE IS POSSIBLE.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. THE GREATER THAN 2 MEV ELECTRON FLUX
WAS HIGH.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET.
