            VARIABILITY OF 59 Aur AND 38 Cnc

    The two stars 59 Aur and 38 Cnc which have been reported to show
light variations in surveys by Danziger and Dickens (ApJ 149,55,1967)
and Breger (ApJ 162, 597, 1970), were observed photoelectrically in
B filter by the authors on the nights of 24 Nov., 1973 and 24 Jan, 1974
with the 38 cm reflector of this observatory, employing an unrefrigerated 
1P21 photomultiplier. The light curves obtained show a variability 
with periods and amplitudes as follows:

    Star       HD       Sp      M_v       P         Amp.

  59 Aur     50018     A7 n    1.33    0d.136      0m.03
  38 Cnc     73575    F0 III   0.66    0d.108      0m.07

    The star 38 Cnc is a member of the Praesepe cluster and its
absolute magnitude M_v is taken from Breger (ApJ 176, 273, 1972). The
positions of these stars in the colour-magnitude diagram (Leung AJ 75,
643,1970) as well as their periods fit well into the period-luminosity 
relationship for Delta Scuti stars given by Leung (loc.cit).
    Further investigations for beating phenomenon and more accurate
period determination are in progress.
