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 144 Publicado el 2200Z a las 24 May 2001IA. Análisis de regiones solares activas y de actividad desde 23-2100Z hasta 24-2100Z Solar activity was moderate. Region 9468 (N05E25)
produced an M1/1n flare at 24/1944Z. Minor centimetric bursts, a
Type II radio sweep (620 km/s), and a CME also accompanied this
flare. Region 9468 is a moderately complex group covering 150
millionths of white light area and produced frequent brightness
fluctuations throughout the period. A pair of long duration C1
events were observed at 24/0706Z and 24/0901Z, and were likely
associated with an impressive CME originating just behind the NE
limb. A weak Type II sweep was observed at 24/1712Z, associated with
a filament eruption and faint CME near the west limb. The largest
region on the visible disk - Region 9463 remains stable in a simple
beta configuration.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. An isolated M-class event is possible from Regions 9463
and 9468.
IIA. Resumen de la actividad geofísica 23-2100Z a 24-2100Z
The geomagnmetic field was quiet to unsettled. We have been under the
influence of a high speed coronal hole stream for almost 40 hours,
but the geomagnetic response so far has been weak.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods
through days one and two. Active to minor storm conditions are
possible on day three in response to the CME at 24/1955Z.
