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 035 Publicado el 2200Z a las 04 FEB 1999IA. Análisis de regiones solares activas y de actividad desde 03-2100Z hasta 04-2100Z SOLAR ACTIVITY WAS LOW. A LONG-DURATION C5 EVENT
OCCURRED FROM 0624 TO 0758Z. X-RAY IMAGE DATA INDICATED THAT THE
SOURCE OF THE ENHANCED X-RAYS WAS FROM BEHIND THE NORTHWEST LIMB.
REGION 8453 (S26E19) CONTINUED TO GROW SLOWLY TODAY AND IS THE ONLY
SUNSPOT REGION CURRENTLY ON THE DISK.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO VERY LOW.
IIA. Resumen de la actividad geofísica 03-2100Z a 04-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. QUIET CONDITIONS
PREVAILED FROM THE START OF THE PERIOD THROUGH ABOUT 1400Z. AFTER
1400Z UNSETTLED CONDITIONS BEGAN AND CONTINUED FOR THE REMAINDER OF
THE DAY. THE SOLAR WIND VELOCITY HAS MOVED UP TO VALUES 50 PERCENT
ABOVE THE 300 KM/S VALUES OF EARLY TODAY.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE FOR TOMORROW AND TREND TO QUIET
TO UNSETTLED BY THE THIRD DAY.
