The early type contact binary system V 382 Cygni

New photometric data set of the early type con- tact binary V 382 Cyg have been analyzed with emphasis on determining the photometric mass ratio of the sys- tem. The result (q =0 :68) supports the value given by Popper & Hill (1991). 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 5: 01 0 6 M=yr of mass transfer from the less massive to the more mas- sive component under the conservative mass transfer hypothesis.
