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 346 Publicado el 2200Z a las 12 DEC 1998IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z SOLAR ACTIVITY WAS LOW. ONLY MINOR C-CLASS X-RAY EVENTS
OCCURRED DURING THIS PERIOD. THE MOST ACTIVE REGIONS WERE 8404
(S22W77), 8408 (S18E01), AND 8409 (S29E13). ALL OF WHICH PRODUCED
MINOR C-CLASS X-RAYS EVENTS AND OPTICAL SUBFLARES. REGION 8408 HAS
GROWN SIGNIFICANTLY SINCE YESTERDAY. CURRENTLY IT IS A 19 SPOT DSO
BETA-GAMMA GROUP. REGION 8411 HAS ALSO SHOWN AN INCREASE IN SIZE AND
NUMBER OF SPOTS, CURRENTLY A 5 SPOT CSO BETA GROUP.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW WITH CONTINUED C-CLASS EVENTS. THERE IS A SLIGHT CHANCE OF AN
ISOLATED M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
THE GEOMAGNETIC FILED WAS UNSETTLED EARLY IN THE PERIOD AND HAS SINCE
BEEN QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
