        REVISED EPHEMERIS FOR NOVA T AURIGAE

       Walker (1) has found that Nova T Aur is an eclipsing binary of
short period. As part of my program of photometry of cataclysmic
variables, this star was observed on three nights in February with
the 36-inch, Cassegrain reflector at Kitt Peak National Observatory,
Tucson, Arizona.

       It was not found possible to reconcile all the observations. If
Walker' s first minimum is omitted, the elements

Hel. Min.= JD 2437614.011 + 0.2043786day x E,

are derived.

     Obviously continued surveillance of this object is warranted.
