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 25 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 145 Publicado el 2200Z a las 25 May 2005IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity continues at very low levels. Occasional
B-class flares were observed in Regions 766 (N14E23) and 767
(S07E26). These two active regions are the only sunspot groups on
the visible disk, and exhibited little change this period. A large
CME off the east limb was observed on LASCO imagery during the
latter half of 24 May. The likely source of this CME was backsided.
IB. Pronóstico de la actividad solar
Solar activity is expected to continue
at very low levels. There is a slight chance for a C-class flare
from Region 767.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic field was quiet. Solar wind speed declined to near
360 km/s. The greater than 2 MeV electron flux at geosynchronous
orbit was at high levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet, with isolated unsettled periods on 26 May.
Occasional active periods are expected on 27 and 28 May as a coronal
hole high speed stream rotates into a geoeffective position.
