New results of studying the variability of line proles in the spectra of bright OBA stars on minute and second time scalesare presented. The observations were carried out in 2015–2021. Nearly 11000 spectra of 22 OBA stars were obtained. Regularvariations of the line proles with minute periods and amplitudes of 1–2% of the continuum level in spectra of the programstars are found.
