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 146 Publicado el 2200Z a las 26 MAY 1999IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z SOLAR ACTIVITY WAS MODERATE. THERE WERE A LARGE NUMBER
OF WEAK C-CLASS X-RAY FLARES, TWO OF WHICH WERE LONG DURATION
EVENTS. THE FIRST LDE WAS AN OPTICALLY UNCORRELATED C1 AT 25/2137Z,
THE SECOND A C2/SF FROM REGION 8550 (S14W12) AT 26/0522Z. IN
ADDITION THERE WAS A TYPE II RADIO SWEEP (SPEED 650 KM/S) CORRELATED
TO A C2/SF FROM REGION 8554 (N26E26) AT 26/0230Z. FINALLY, THE
STRONGEST FLARE WAS AN M1/2N FLARE FROM REGION 8552 (N11E41) AT
26/1932Z. ONE REGION, 8555 (N16E75), WAS NUMBERED TODAY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
WITH A CHANCE OF AN ISOLATED M-CLASS FLARE.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH A CHANCE FOR ACTIVE
CONDITIONS LATE TOMORROW. THE INFLUENCE OF A RECURRENT CORONAL HOLE
IS EXPECTED DURING THIS TIME.
