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 137 Publicado el 2200Z a las 17 May 2001IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity was moderate due to a single M-class
event, an M1/1f flare from Region 9455 (S16W66) at 17/1652. Regions
9451 (S20W90+), 9454 (N14W22), and 9455 all produced C-class events
during the period. Region 9455 produced a C9/1f at the end of the
reporting period. Region 9461 (N18E49), returning Region 9433
(responsible for major flares during its previous two rotations),
continued to show little activity and is currently a 4-spot D-type
group.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels. Regions 9454 and 9455 could produce isolated
M-class events during the forecast period.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field ranged from quiet to unsettled levels. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels with a possibility of
isolated active periods at high latitudes on 18 May. The greater
than 2 MeV electron flux may reach high levels during the period.
