Photometric studies of the dwarf nova V503 Cygni have been conducted for 29 nights at the Crimean Astrophysical Observatory and at the Terskol Observatory during 2010. We detected none of the socalled “negative” superhumps observed previously in the quiet state and in ordinary (short) outbursts [1]. Instead, during the ordinary outbursts and in a superoutburst and for some time after its termination, we recorded “positive” superhumps. At other times outside the outbursts we have for the first time detected oscillations in the brightness at the orbital period of 0.077760(3) days that have not been observed photometrically before.
