        A REVISED EPHEMERIS FOR AN URSAE MAJORIS




   Following publication of my previous note (Mumford, 1976) on
this object, Prof. Kukarkin very kindly provided a copy of Shugarov's 
(1975) original contribution. The light elements that best
fit the previously given epoch, the photoelectric observations
made at Kitt Peak, and currently accepted models of novalike 
variables requires that the period be one-half of that given 
previously.

   Min. J.D. hel. = 2442502.285 + 0.0796894d E.
   With these elements, the following residuals are calculated.

           JD hel.   Cycle    O-C
          2442000 +

          502.285    Epoch
          805.9813   3811     0.0000d
          806.9378   3823    +0.0002
          807.7345   3833     0.0000
          807.8938   3835     0.0000

   This result is in keeping with a suggestion made by Shugarov.
