Scientific paper

Photometry of Tau Persei was obtained during ingress and egress of its 1989 eclipse and analyzed using a simple geometrical model. The estimated depths of eclipse are 0.62, 0.43, and 0.23 mag in U, B, and V, respectively, which imply that all but about 17 percent of the A-type secondary is covered by the G-giant primary at minimum light. When combined with observations from the 1984 eclipse, the new data yield a photometric period of 1515.869 + or - 0.059 days.
