Abstract

 

The published period (199 days) for V461 Cyg has been confirmed, while the period of V462 Cyg proves to be 371 days and is changing. A variable star discovered on Nantucket plates in 1975 is found to have a period of 107.6 days with a photographic amplitude of about 2.5 mag. V381 Cyg was examined on nearly 1000 plates. The published approximate period of 4.88 days could not be confirmed. No new period has yet been determined, but it cannot be greater than about 3 days.
