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 139 Publicado el 2200Z a las 19 May 2001IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was low. Only occasional C-class flares
occurred during the period. The largest event was an optically
uncorrelated C6 flare at 19/1438 UTC. This was accompanied by a Type
II radio sweep (470 km/s). Although imagery was non-conclusive, it
appears that this event originated in Region 9455 (S17W90+) which
was at or near the west limb at the time. A non-earth directed
coronal mass ejection from this event was detected by the LASCO/SOHO
spacecraft. Two new regions were numbered, 9463 (N07E70) and 9464
(S11E70).
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance of isolated M-class events.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet to active. The greater than 2 MeV
electron flux at geosynchronous orbit reached moderate levels during
the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled. The greater than 2 MeV electron
flux can be expected to reach moderate levels during the forecast
period.
