dc.description.abstract	In order to search for rapid Hα variability in Be stars, a series of Hα profiles were observed on a time scale of few minutes for 28 Eri, X Oph, 66 Oph and π Aqr. In total, 95 and 54 Hα profiles were obtained for the program Be stars and the standard stars respectively. The theoretical expression of Chalabaev and Maillard (1983) was used to estimate the uncertainty of the Hα equivalent width measurements. It is found that rapid variations of continuum level and equivalent widths of Hα line are absent.	en
