Abstract
This paper presents the result of UBV photoelectric photometry of VV Cephei. The contact times are determined from the B-V and U-B curves. The epoch of mideclipse is JD 2443361 in agreement with prediction. The unequal depths of the falling and rising branches of the colour curves can be explained by gas streaming from the M-type supergiant component. The radius of the M-type supergiant is about 1860 R and its atmosphere has a thickness of 450 R.
