Large-scale moving ionospheric disturbances during a magnetic storm on October 29-30, 2003 according to the Kamchatka GPS station network.

The Kamchatka regional network of stationary receiving stations of GPS navigation system signals (KAMNET), developed for geodynamic studies, is being used for the first time to study the time-space characteristics of disturbances of total electron content in the ionosphere during magnetic storms. This paper presents the results of measurements of the main parameters of large-scale moving ionospheric disturbances (LSMID) during a powerful magnetic storm on October 29-31, 2003 in comparison with LSMID characteristics for large magnetic storms on April 6 and July 15, 2000. The analysis of GPS data showed that the main phase of all analyzed storms is characterized by the formation of large-scale waves with the period of about 1 hour, which propagate in the equatorial direction from a source located in the auroral zone, with an average speed of about 500 m/s.
