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 068 Publicado el 2200Z a las 09 MAR 1999IA. Análisis de regiones solares activas y de actividad desde 08-2100Z hasta 09-2100Z SOLAR ACTIVITY WAS LOW. REGION 8484 PRODUCED TWO
C-CLASS SUBFLARES: THE FIRST WAS A C2/1F AT 1830Z AND THE SECOND WAS
A C1/SF AT 2010Z. THE GROUP IS AN ACTIVE, BUT RELATIVELY SMALL
D-TYPE SUNSPOT REGION. REGION 8485 (N22E53) SHOWED FREQUENT
BRIGHTENINGS DURING THE PAST 24 HOURS BUT ONLY PRODUCED ONE
SUB-FAINT FLARE. THE OTHER SUNSPOT REGIONS WERE STABLE AND QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
THERE IS A SLIGHT CHANCE, HOWEVER, FOR AN ISOLATED M-CLASS EVENT
FROM 8484 OR 8477 (S28W33).
IIA. Resumen de la actividad geofísica 08-2100Z a 09-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO STORM LEVELS DURING THE
PAST 24 HOURS. AN INITIALLY QUIET FIELD BECAME ACTIVE AROUND
09/0000UT, AND INTENSIFIED TO MINOR STORM (WITH SOME HIGH LATITUDE
MAJOR STORM PERIODS) BETWEEN 0600-1330 UT. CONDITIONS SUBSIDED
GRADUALLY, WITH UNSETTLED CONDITIONS PREVAILING BY 09/2100Z. THE
GREATER THAN 2 MEV ELECTRONS AT GEOSYNCHRONOUS ORBIT ATTAINED HIGH
LEVELS DURING THE PAST 24 HOURS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED FOR THE NEXT 24 HOURS. QUIET TO
UNSETTLED CONDITIONS SHOULD PREVAIL FOR THE SECOND AND THIRD DAYS.
