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 230 Publicado el 2200Z a las 18 AUG 1999IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY WAS LOW. A LONG-DURATION C7 EVENT WAS
THE HIGHLIGHT OF THE PERIOD, BUT THE EVENT WAS NOT OPTICALLY
OBSERVED. REGION 8668 (N22E15) REMAINS THE DOMINANT ACTIVE CENTER IN
WHITE LIGHT AND H-ALPHA. NEWLY ASSIGNED REGION 8672 (N12E01) EMERGED
JUST WEST OF 8668 AND PRODUCED A SUBFLARE AT 1154Z.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
HOWEVER, REGION 8668 MAY PRODUCE AN ISOLATED M-CLASS EVENT DURING
THE NEXT THREE DAYS.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD REMAINED AT ACTIVE TO MINOR STORM LEVELS. THIS
DISTURBANCE, RELATED TO A HIGH SPEED SOLAR WIND STREAM, BEGAN IN THE
EARLY PART OF 16 AUGUST. SPEEDS CONTINUED IN THE 600-700 KM/S RANGE
MOST OF TODAY. THE GREATER THAN 2 MEV GEOSYNCHRONOUS ELECTRON FLUX
ATTAINED HIGH LEVELS AROUND 1200Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE ON 19 AUGUST. SOLAR WIND SPEEDS
SHOULD DIMINISH TO A MORE NORMAL RANGE THEN, AND ACTIVITY SHOULD
DECLINE. UNSETTLED CONDITIONS SHOULD PREVAIL AT THE END OF THE
INTERVAL.
