Measure Technique

Hemos utilizado la Técnica de medición de intermitencia local (local Intermittency Measure Technique) basada en la técnica de la transformada de wavelet para estudiar las fluctuaciones de velocidad en el plasma, medidas por experimento de espectrómetro de iones de satélite CLUSTER, durante la tormenta geomagnética de 24-28 de agosto de 2005. Los resultados obtenidos mostraron un aumento significativo de nivel de turbulencia intermitente al final de la fase principal. Esto puede estar relacionado con un aumento significativo en la actividad de las subtormentas y estiramiento de las líneas del campo geomagnético observado en la fase principal. Este hecho es importante para la comprensión de la naturaleza de las tormentas geomagnéticas.

Statistical auroral distributions are used in combination with an empirical model of the Earth's magnetic field in an attempt to determine the large-scale magnetospheric source regions for various types of auroral luminosity. The narrow ring of structured auroral emissions during magnetically quiet intervals appears to be associated with the inner region of the nightside central plasma sheet and the dayside entry layer. Under active conditions these discrete structures expand to fill the entire central plasma sheet. The high-altitude boundary plasma sheet on the other hand is more likely to be related to diffuse auroral emissions poleward of this "oval" and to high-latitude polar auroral arcs. Under this scenario, the region of the magnetosphere bounded by the inner edge of the tail current sheet, the plasmasphere, and the dayside entry layer is the source region for the most equatorward diffuse auroral precipitation.
