* Discovery Information

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ken-ichi Kadota, Ageo City, Saitama, Japan, then confirmed by Seiichi Yoshida.

V559 Cyg is 1.4 arcmin from MisV0774. No star brighter than 14.6 mag was detected at the catalogued position of V559 Cyg on our unfiltered CCD images. However, considering the faint photographic magnitude range in the GCVS, between 16.2 mag and fainter than 17.6 mag, and the large distance, MisV0774 is probably another new variable object.

* Special Notes

John Greaves reported that the position of V559 Cyg was revised in IBVS 4905 and came to coincide with MisV0774.
