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 079 Publicado el 2200Z a las 20 MAR 1998IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z SOLAR ACTIVITY WAS LOW. REGION 8179 (S22W69) PRODUCED
TWO C-CLASS FLARES, A C2.8/SF AT 20/1857Z AND A C1/SF AT 20/2030Z,
PLUS A FEW VERY MINOR SUBFAINT FLARES. SEVEN UNCORRELATED C-CLASS
X-RAY BURSTS WERE DETECTED AS WELL. THESE MAY HAVE ORIGINATED JUST
BEHIND THE SE LIMB (S26) WHERE AN ACTIVE SURGE REGION WAS VISIBLE
MOST OF THE DAY AND AN ERUPTIVE PROMINENCE WAS OBSERVED ENDING AT
20/1234Z. THIS IS LIKELY THE RETURN OF REGION 8171 (S24L235), BUT NO
SPOTS HAVE APPEARED ON THE LIMB YET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8179, STILL GROWING SLOWLY, HAS A GOOD CHANCE OF
C-CLASS ACTIVITY, A FAIR CHANCE OF ISOLATED M-CLASS ACTIVITY AND A
SMALL CHANCE OF PRODUCING AN ISOLATED X-CLASS EVENT.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED. THE GREATER THAN
TWO MEV ENERGETIC ELECTRON FLUX RANGED FROM MODERATE TO HIGH.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE ENTIRE FORECAST PERIOD.
