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 294 Publicado el 2200Z a las 21 OCT 1998IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST X-RAY FLARE OF THE
PAST DAY WAS A LONG DURATION C7 THAT, FROM EIT IMAGES, APPARENTLY
OCCURRED FROM BEHIND THE SOUTHWEST LIMB. THIS FLARE WAS ASSOCIATED
WITH A WEAK TYPE II/IV RADIO SWEEP AND CORONAL LOOPS. REGION 8365
(S28W24) HAS BEEN EMERGING RAPIDLY, MORE THAN DOUBLING ITS SUNSPOT
AREA. THIS REGION HAS STARTED TO GENERATE SMALL FLARES; THE LARGEST
SO FAR BEING A C1/SF AT 21/1132Z. NEW REGION 8367 (N16E00) EMERGED
JUST TO THE SOUTHEAST OF REGION 8362 (N18W08).
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
C-CLASS ACTIVITY IS POSSIBLE FROM REGION 8361 (N15W94), AS IT ROUNDS
THE WEST LIMB, AND REGION 8365.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE. THIS ACTIVITY IS
BELIEVED TO BE THE RESULT OF ALFVENIC WAVE ACTIVITY ASSOCIATED WITH
A HIGH-SPEED STREAM FROM THE NORTHERN POLAR CORONAL HOLE. THE 2 MEV
ELECTRON FLUX WAS MODERATE TO HIGH.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT 24 HOURS, BECOMING
QUIET TO UNSETTLED.
