We present some results of observations of the ionosphere disturbances which arose during the launching site and flight of rocket the «Proton». The rocket was launched from the Baikonur site at 22:31 UT on 29 March 2005 during a moderate magnetic storm (Kpmax = 4). Disturbances from the rocket were superimposed on disturbances caused by the magnetic storm. The disturbances which arose in the ionosphere with delays of 11-26 and 87-102 min were connected with the rocket launching. Velocities of 1.5-3.5 km/s and 375-440 m/s corresponded to these delays. Such velocities can be attributed to slow MHD or magnetico-gradient waves and internal gravitational waves. The relative amplitude of disturbances of electron density and their period were equal to 2.5-5 % and 90 min, respectively.
