Abstract
From a discussion of narrow-band observations of Zeta Aurigae in the 1963–64 eclipse, the duration of totality has been precisely found to be ≦36.901 days, which is appreciably smaller than the value 37.48 days currently used. The present result reveals that a hypothesis of gradual expansion of the K-type supergiant component could not be tenable.
