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 279 Publicado el 2200Z a las 06 OCT 1999IA. Análisis de regiones solares activas y de actividad desde 05-2100Z hasta 06-2100Z SOLAR ACTIVITY REMAINED LOW. REGION 8720 (N13E29)
PRODUCED SEVERAL SMALL C-CLASS SUBFLARES DURING THE PERIOD. SEVERAL
NEW SPOTS DEVELOPED IN THIS RE-EMERGING REGION. OTHER REGIONS WERE
PREDOMINANTLY STABLE. DURING THE PERIOD, A MODERATELY LARGE REGION
OF ENHANCED X-RAY EMISSION BECAME VISIBLE BETWEEN NE20-30 INDICATING
THE IMMINENT ARRIVAL OF ANOTHER SUNSPOT REGION TO THE VISIBLE DISK.
A LARGE CORONAL MASS EJECTION CENTERED NEAR SE45 BEGAN NEAR
06/0000Z. THE PROPAGATION VELOCITY WAS VERY SLOW AND TRAJECTORY WAS
RADIAL.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD REMAIN GENERALLY
LOW FOR THE NEXT THREE DAYS. C-CLASS EVENTS ARE POSSIBLE FROM
SEVERAL REGIONS ON THE DISK. THERE IS A SLIGHT POSSIBILITY OF A LOW
LEVEL M-CLASS EVENT DURING THE PERIOD. THE NEW REGION OVER THE
NORTHEAST LIMB MAY ELEVATE ACTIVITY LEVELS SLIGHTLY BUT IT IS
DIFFICULT AT THIS TIME TO ASSESS ITS POTENTIAL.
IIA. Resumen de la actividad geofísica 05-2100Z a 06-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. SOLAR WIND VELOCITY
DROPPED BELOW 500 KM/S DURING THE LATTER HALF OF THE DAY.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BECOME QUIET TO ACTIVE DURING THE NEXT THREE DAYS. A
CORONAL HOLE RELATED HIGH SPEED STREAM IS EXPECTED TO RESUME DURING
THE PERIOD.
