Travelling ionospheric disturbances deduced from simultaneous satellite beacon observations in Graz/Austria and Neustrelitz/GDR
Abstract
Ionospheric electron content data have been obtained in Graz/Austria and Neustrelitz/GDR. At both stations the VHF-beacon signal of the geostationary satellite Sirio-1 (15 deg W) has been used to calculate the ionospheric electron content from Faraday rotation observations for comparative studies. Differential Doppler measurements of NNS signals carried out in Graz proved additional information concerning the variation of ionospheric electron content with latitude. The construction of a complex TID structure for the night of April 25/26, 1981 indicates the propagation of a Large Scale Travelling Ionospheric Disturbance from northeast to southwest. This type of perturbation has been assumed to be associated with geomagnetic storms.
