Scientific paper

Searching for optical light variability of LS I +61°303, the radio burster with the period 26d.52, has been carried out. During the 35d observational cycle, the amplitude of light variations reached ≡0m.1 in W, B, V, R. Sharp falls of light, with subsequent return to the mean level on a time-scale of 10 - 15 min, have been noticed. The position of LS I +61°303 (=V615 Cas) on the colour-colour diagram (W-B, B-V) corresponds to a B0e star with colour excess E(B-V) = 1m.07.
