Abstract
A radial velocity study resolves a long-standing aliasing problem and shows that the orbital period of the dwarf nova WW Ceti is 0.17578+/-0 .00013 d (4.22 h). Its long-term light curves from RoboScope, AAVSO, H arvard archive, and VSS, RASNZ observations are examined. WW Ceti does not have the characteristic standstills of the Z Cam stars, but does wander in quiescence by well over 1 mag. (C) 1996 American Astronomica l Society.
