AY Lyr
------
I received an e-mail from Japan, with a question concerning 
the orbital period of the dwarf nova AY Lyr.

According to (1) the orbital period of AY Lyr is 1.81 hours.

Reference:
(1) Hassall, B.J.M., "Ultra-Violet Radiation from Dwarf Nova Discs",
published in "Cataclysmic Variables and Low-Mass X-Ray Binaries",
edited by D.Q. Lamb and J. Patterson (Proceedings of the 7th North
American Workshop, held in Cambridge, Mass., USA, January 12-15,
1983). ISBN 90-277-1947-0. D. Reidel Publishing Company, Holland, 1985.


By the way, it would be interesting to see an updated list of
orbital periods and superhump periods for SU UMa stars!
