WZ Sge: humps and eclipses (Sep. 23) Dear Colleagues, The remarkable profile seen on Sep. 23 closely resembles that observed on Sep. 18. This supports that earlier suggestion of the shortening of the beat period. The beats now occur every 5 days. The shorter beat period indicates a higher angular velocity of disk precession -- what's ongoing? Regards Taichi Kato VSNET Collaboration team
