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 072 Publicado el 2200Z a las 13 MAR 1999IA. Análisis de regiones solares activas y de actividad desde 12-2100Z hasta 13-2100Z SOLAR ACTIVITY INCREASED TO MODERATE LEVELS. REGION
8487 (N17E39) REMAINED A RELATIVELY SMALL D-TYPE GROUP AND SHOWED
MINOR PENUMBRAL GROWTH AS WELL AS SOME MAGNETIC SHEAR IN THE
VICINITY OF THE DOMINANT LEADER SPOT. IT PRODUCED AN IMPULSIVE M1/1N
AT 13/2034Z AND NUMEROUS SUBFLARES EARLIER IN THE DAY, A FEW OF
WHICH REACHED C-CLASS. NONE OF THESE FLARES WERE IMPRESSIVE IN RADIO
EMISSION. REGION 8485 (N23E00) REMAINED A MODERATE-SIZED E-TYPE
GROUP WITH SOME MIXED POLARITIES. IT WAS GENERALLY STABLE AND
PRODUCED ISOLATED SUBFARES. THE REMAINING REGIONS WERE QUIET AND
STABLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE AT
MOSTLY LOW LEVELS. HOWEVER, ANOTHER ISOLATED M-CLASS FLARE COULD
OCCUR FROM REGION 8487 SOMETIME DURING THE PERIOD. REGION 8485 ALSO
PROVIDES A SLIGHT CHANCE FOR AN ISOLATED M-CLASS FLARE.
IIA. Resumen de la actividad geofísica 12-2100Z a 13-2100Z
GEOMAGNETIC FIELD ACTIVITY INCREASED TO UNSETTLED TO ACTIVE LEVELS
DURING 13/1200 - 1400Z. OTHERWISE, THE FIELD WAS AT QUIET TO
UNSETTLED LEVELS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT UNSETTLED TO ACTIVE LEVELS THROUGH THE PERIOD.
BRIEF MINOR STORM PERIODS ARE ALSO POSSIBLE. THIS ACTIVITY IS
EXPECTED IN RESPONSE TO CME EFFECTS. AN ISOLATED, POSITIVE POLARITY
CORONAL HOLE MAY ALSO DISTURB THE FIELD SOMETIME DURING THE PERIOD.
