Scientific paper

A search for rapid variability of H-alpha with a time resolution from 30
to 45 seconds is performed for Phi Per. In total, 42 spectra in H-alpha
were obtained during three nights. Results show the presence of rapid
irregular variability (time scale of a few minutes) of the equivalent
width of the H-alpha line in Phi Per.
