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 074 Publicado el 2200Z a las 15 MAR 1999IA. Análisis de regiones solares activas y de actividad desde 14-2100Z hasta 15-2100Z SOLAR ACTIVITY CONTINUED AT MODERATE LEVELS. REGION
8487 (N16E11) SHOWED A SMALL INCREASE IN AREA AND MAGNETIC FIELD
INTENSITY AND PRODUCED AN M1/1N PARALLEL-RIBBON FLARE AT 15/0336Z
ASSOCIATED WITH A TYPE II RADIO SWEEP. SLOW GROWTH IN PENUMBRAL
COVERAGE AND MAGNETIC FIELD INTENSITY ALSO OCCURRED WITHIN REGION
8485 (N23W25). IT REMAINED A LARGE F-TYPE SPOT GROUP WITH MIXED
POLARITIES AND PRODUCED ISOLATED B- AND C-CLASS SUBFLARES. THE
REMAINING SPOT GROUPS WERE QUIET AND STABLE. NO NEW REGIONS WERE
ASSIGNED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGIONS 8485 AND 8487 MAY PRODUCE ISOLATED M-CLASS
FLARES SOMETIME DURING THE PERIOD.
IIA. Resumen de la actividad geofísica 14-2100Z a 15-2100Z
THE GEOMAGNETIC FIELD VARIED FROM QUIET TO ACTIVE LEVELS AT ALL
LATITUDES AND SHOWED A DECREASING TREND AFTER 15/1600Z. RECENT
ACTIVE PERIODS APPEAR TO BE IN RESPONSE TO A HIGH-SPEED CORONAL HOLE
WINDSTREAM.
IIB. Pronóstico de la actividad geofísica
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO CONTINUE AT QUIET TO ACTIVE LEVELS DURING THE FIRST DAY
OF THE FORECAST PERIOD, THEN DECLINE TO QUIET TO UNSETTLED LEVELS
FOR THE REST OF THE PERIOD.
