XZ Eri: further observation from Donn Starkey Dear Colleagues, We have received a new run from Donn Starkey. The eclipses are prominent, and the phase of the superhumps have further moved. The profile of the eclipses is highly asymmetric, indicating the non-axisymmetric brightness distribution of the accretion disk (thereby producing superhumps). The eclipse ephemeris earlier today have several minutes different from the observation. We will probably need more coverage to refine the eclipse ephemeris before making an update. The object is perfectly a winner! Regards, Taichi Kato VSNET Collaboration team
