SINOPSIS

Observational results are presented concerning perturbations in the ionosphere associated with the launches and flights of the "Proton" rocket on March 29, 2005 and December 14, 2009. The rocket launch-produced disturbances arose 10 to 30 and 90 to 110 minutes after the launch. Recorded first was a negative perturbation of the electron density characterized by the average speed about 2 km/s. The next perturbation was a quasi-periodic one moving at a speed about 400 m/s. The magnitude of relative variations in the electron density reached 26 %.
