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 138 Publicado el 2200Z a las 18 May 2001

IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z

Solar activity was low. Region 9461 (N19E39) was the most active region during the period, producing a C4/Sf event at 17/2142 UTC. The largest event was an optically uncorrelated C6 flare at 18/0640 UTC. Regions 9454 (N14W33) and 9455 (S17W80) began to show signs of decay and decreased activity today. One new region was numbered overnight, 9462 (N16E65).
IB. Pronóstico de la actividad solar
Solar activity is expected to be mostly low. Region 9461 could possibly produce isolated M-class events.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
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 a quiet to unsettled levels. The greater than 2 MeV electron flux may reach moderate to high levels during the period.
