The early type contact binary system V 382 Cygni

New photometric data set of the early type contact binary V382 Cyg have bee n analyzed with emphasis on determining the photometric mass ratio of the s ystem. The result (q = 0.68) supports the value given by Popper & Hill (199 1). A study of the system using new data shows a period increase of about 3 .28 s per century, which corresponds to a very large rate similar to 5.0 10 (-6) M./yr of mass transfer from the less massive to the more massive compo nent under the conservative mass transfer hypothesis.
