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
::::::::::::::::::CORRECTED COPY::::::::::::::::: SDF Número 346 Publicado el 2200Z a las 12 DEC 1997IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z SOLAR ACTIVITY WAS LOW. REGION 8119 (N33W49), AN 8 SPOT
DAO GROUP, PRODUCED A C1/SF AT 12/0713UT. REGION 8122 (N31W18), A 14
SPOT DSO GROUP, PRODUCED OCCASIONAL B-CLASS SUBFLARES EARLY IN THE
PERIOD. BOTH THESE REGIONS ARE THE LIKELY SOURCES OF THREE
UNCORRELATED C-CLASS FLARES THAT OCCURRED BETWEEN 12/1046 -
12/1218UT. ALL THREE OF THESE C-CLASS FLARES APPEARED DURING A
PERIOD OF SLIGHTLY ENHANCED X-RAY EMISSIONS BETWEEN 12/1000 -
12/1300UT. THE ENHANCMENT IS POSSIBLY DUE TO THE DISAPPEARANCE OF A
LONG, APPROXIMATELY 50 DEGREE, FRAGMENTED FILAMENT FROM THE SW
QUADRANT. THE REMAINING REGIONS HAVE BEEN QUIET AND STABLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW TO LOW. REGION 8119 EXHIBITED NO SIGNIFICANT CHANGE SINCE
YESTERDAY BUT IS STILL CAPABLE OF PRODUCING ISOLATED C-CLASS
FLARING. REGION 8122 HAS STABILIZED SINCE ITS DRAMATIC GROWTH
YESTERDAY AND IS ALSO CAPABLE OF PRODUCING ISOLATED C-CLASS FLARING.
OLD REGION 8108 IS ROUNDING THE EAST LIMB BUT APPEARS MUCH WEAKER
THAN ITS LAST TRANSIT ON THE VISIBLE DISK.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. THE GREATER THAN 2 MEV ELECTRON
FLUX REACHED HIGH LEVELS LATE IN THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET FOR THE NEXT THREE DAYS.
