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 Apr 19 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 109 Publicado el 2200Z a las 19 Apr 2005IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was very low. Region 755 (S12E49),
which was responsible for three C-class flares on 17 April,
continues to decay. A CME was observed on LASCO imagery at 19/1226
UTC directed to the northwest. The CME most likely occurred on the
backside and is not expected to be geoeffective. No new regions
were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet to unsettled with an isolated active
period between 0600 UTC and 0900 UTC on 19 April. The greater than
2 MeV electron flux at geosynchronous orbit was at high levels again
today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with the possibility of isolated
active conditions on 20 and 21 April. On 22 April, there is a
chance for increased active periods due to a recurrent coronal hole
high speed stream moving into geoeffective position.
