Scientific paper

Results of photoelectric UBVR-observations of T Tauri carried out in October - November 1987 with the 1-m reflector of the Sanglok Observatory are given. These observations confirm the existence of light variations with the period of 2d.8. The amplitudes of sinusoidal curves which give the best fit with observations are 0m.123, 0m.084, 0m.070, 0m.057 in the UBVR bands, correspondingly. Such light and colour variations may be explained by the rotational modulation due to dark (or bright) spots on the stellar surface.
