        PHOTOGRAPHIC LIGHTCURVE OF HBV 476

      A total of 144 plates was measured in order to
establish the lightcurve of this Cepheid variable. Using
the preliminary light elements quoted in an earlier paper
(IBVS no. 506) a mean lightcurve was obtained. From this and
the individual measurements 12 epochs of maximum brightness 
could be determined. They are given in the following
table together with 4 epochs of maximum derived in the same
way from photoelectric observations obtained with the 60 cm
reflector at Hamburg.

      A least-square-solution of all times of maximum
gave the following elements together with their mean errors

      Max = 244 0935.527 + 2.114 0314d E
                     +-9         +-21

leading to the residuals "O - C" in the above table.
Using these light elements and forming normal points, a 
lightcurve shown in the Figure could be established.

I am indebted to Professor Dr. A.A. Wachmann for having lead
my interest to this variable and for putting his photographic 
and photoelectric observations at my disposal.
