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 de actividad Solar-Geofísica 2005 May 18 2210 UTC# Prepared jointly by the U.S. Dept. of Commerce, NOAA, #Space Environment Center and the U.S. Air Force. #
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 138 Publicado el 2200Z a las 18 May 2005IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was low. Region 763 (S16W24) was
responsible for three low level C-flares. This region continues to
decay. A CME off the SW limb was observed today on LASCO imagery at
18/0206 UTC, but does not appear to be Earth directed.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low with a chance for an isolated M-flare.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was quiet to active. Solar wind speed at ACE
has been variable between 450 km/s and 550 km/s. The greater than 2
MeV electron flux at geosynchronous orbit was high again today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active on 19 May as a faint full halo CME,
from 17 May, may arrive late in the day. Unsettled conditions are
expected on 20 May. Quiet to unsettled conditions are expected on
21 May.
