During many recent years, from 1973, the search for short-term variations in the spectrum of Ap-stars has been carried out at the Crimean Astrophysical Observatory. Some results are presented in the poster dedicated to 53CAM observations. Spectral observations of the magnetic star 53CAM with time resolution of about I min were supplemented by the narrow-band photometrical observations within the framework of the cooperative program of the magnetic stars observations, started in 1979.
