\title{FOR THE NEW CEPHEID VARIABLE STAR GSC\,3596.0433}

\begintext

Recently Antipin (1996) has analysed photographic archival plates
at Sternberg Astronomical Institute of Moscow and found that
the star GSC\,3596.0433 is a Cepheid variable with the elements:

\centerline{Max JD$_{hel}$ = 2447450.22 + 2.41827 $\times$ E}
\vskip 1mm

We observed this Cepheid photoelectrically at Mt. Maidanak
observatory  in August 1996 using
the 60-cm reflector; a total of 39 $BVR_{\rm c}$
measurements were obtained (Table 1), the accuracy
of the individual data is near $\pm 0^{m}.01$ in  $V$ and
near $\pm$ 0\fm 02 in $B-V$ and $V-R_{\rm c}$.
Above elements are used in Figure 1 for plotting our
observations. According to our data, the amplitude of the light
curve is  0\fm 57 in $V$, 0\fm 25  in $B-V$ and 0\fm 13 
in $V-R_c$.
