\IBVSTrem{
The star was estimated on 410 plates taken during JD\,2437136--49104.
Periodic variability with a light curve typical of a classical Cepheid
was found. The light elements are the following:
$${\rm JD_{max}} = 2441566.32 + 32\fday 071\times E.$$
The range of variability is 14\fmm 7--15\fmm 6. $M-m=0.\!\!^{\rm p}30$.}
