In the 1974 eclipse of Zeta Aurigae the satellite line of the Ca i intercombination line at 6572 Å appeared in all the phases observed, i.e., near the mid-eclipse and egress, although its equivalent width, ˜100 200 mÅ, and velocity deviation, ˜-20 im s-1, from the principal line were considerably less than those for the satellite line found just after the fourth contact of the 1971 72 eclipse. 31 Cygni also showed a similar satellite line to Zeta Aurigae's in the 1974 eclipse, not only in the 1972 eclipse but also outside the eclipse. These satellite lines should be due to the circumstellar gas expanding from the binary systems.
