Large-Scale Traveling Ionospheric Disturbances during the Strong Magnetic Storm of October 29-30, 2003, according to Data of the Kamchatka Network of GPS Stations.

Kamchatka regional network of stationary receiving GPS stations (KAMNET) designed for geodynamic studies is, for the first time, used to study the spatial-temporal characteristics of the total electron content disturbances in the ionosphere during magnetic storms. The results of measurements of the main parameters of large-scale traveling ionospheric disturbances (LSTIDs) during the strong magnetic storm of October 29-30, 2003, are shown in this paper in comparison with the LSTID characteristics for the magnetic storms of April 6, 2000, and July 15, 2000. An analysis of the GPS data showed that solitary large-scale waves lasted for about 1 h were usually generated at the main phase of all analyzed storms. The waves propagated equatorward from the source located in the auroral region at a velocity from 500 to 1000 m/s.
