Sažetak
We investigate the character of light variability of the bright Be star OT Gem. Two phases of the long-term light changes were distinguished: - a quiet phase which is characterized by mild light changes; and - an active phase in which the sudden increase of brightness up to 0.4 in V occur. During the active phase, a cyclic oscillation of brightness of a period between 70 and 80 days is present, with the mosr probable value being 71.89 days. A positive correlation was found between the light and colour variations and the emission strength in both phases.
