Recently, we investigated the variability of line profiles of selected OBA stars with the multi-mode focal reducer SCORPIO on the SAO RAS 6-meter telescope (BTA). We discovered regular variations of the H and He lines in the spectra of the O-type star HD 93521 (O9.5 III) with periods of ˜4-5 and ˜32-36 minutes. A possible origin of short time-scale spectral variations is discussed. ",
