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 351 Publicado el 2200Z a las 17 DEC 1998IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z SOLAR ACTIVITY WAS MODERATE WITH SEVERAL C-CLASS X-RAY
EVENTS AND ONE ISOLATED M-CLASS X-RAY FLARE DURING THE PERIOD.
REGION 8409 (S28W52) PRODUCED A M3/1N EVENT AT 17/0745Z WITH AN
ASSOCIATED TYPE II SWEEP. THE TYPE II SPEED WAS ESTIMATED AT 500
KM/S. A 230 SFU TENFLARE WAS ALSO DETECTED DURING THE M3 EVENT. AT
17/1418Z, REGION 8409 PRODUCED A C7/SN EVENT. AN ASSOCIATED TYPE II
SWEEP WITH AN ESTIMATED SPEED OF 600 KM/S WAS OBSERVED. REGION 8415
(N19E70) WAS NUMBERED AND IS CURRENTLY A BXO BETA SPOT GROUP WITH
SEVEN SPOTS. AT 17/1753Z, REGION 8415 PRODUCED A C6/1F EVENT.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
WITH CONTINUED C-CLASS EVENTS. THERE IS A CHANCE FOR AN ISOLATED
M-CLASS X-RAY EVENT OUT OF REGION 8409.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. NO FURTHER AFFECTS WERE OBSERVED
FROM THE CORONAL HOLE IN THE NORTHERN HEMISPHERE DURING THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET DURING THE FIRST DAY OF THE PERIOD BECOMING
QUIET TO UNSETTLED DURING THE LAST TWO DAYS OF THE PERIOD.
