\IBVSTrem{ The brightness of the newly discovered variable star was
estimated by eye on 599 plates from Moscow archive, JD\,2432853--49633.
Periodic variability typical of a classical Cepheid was revealed.
The light elements are the following:
$${\rm JD_{max}} = 2442486.26 + 7\fday 67786\times E.$$
The variability range is 14\fmm 95--15\fmm 70. ${\rm
Max-min}=0\fper35$. The phased light curve (Fig.~1) shows a hump on
descending branch, in agreement with the Hertzsprung progression for this
value of period.}
