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 265 Publicado el 2200Z a las 22 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z SOLAR ACTIVITY WAS LOW. A C5/1F FLARE FROM REGION 8706
(N19E38) AT 1340Z WAS THE LARGEST EVENT OF THE DAY. NEWLY ASSIGNED
REGION 8708 (S09E55) PRODUCED FREQUENT SUBFLARES DURING THE FIRST
HALF OF THE INTERVAL. ANOTHER NEW REGION, 8707 (S07W08) HAS BEEN
QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO MINOR STORM LEVELS. A SMALL
SUDDEN IMPULSE, MEASURED AT BOULDER TO BE 8 NANOTESLA, OCCURRED AT
1222Z. SATELLITE DATA FROM ACE SHOWED THE PASSAGE OF AN
INTERPLANETARY SHOCK JUST PRIOR. SOLAR WIND SPEEDS NEAR 600 KM/S,
AND BZ MEASURING NEAR -15 NT ARE NOW OCCURRING. THE SOLAR ORIGIN OF
THIS EJECTION IS NOT WELL-ESTABLISHED.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT ACTIVE TO MINOR STORM LEVELS FOR THE NEXT 24 HOURS.
SOLAR WIND DATA INDICATE HIGH SPEEDS AND RELATIVELY STRONG SOUTHWARD
MAGNETIC FIELDS. UNSETTLED TO ACTIVE CONDITIONS SHOULD PREVAIL THE
LAST TWO DAYS.
