     PHOTOELECTRIC BVR OBSERVATIONS OF RR LYRAE STAR V381 Cyg


  V381 Cyg is an RRab star with elements (Kholopov et al., 1985):

           Max=JD hel 2439005.667+0.6100146d x E   (1)

This star has not been observed photoelectrically before.  We have observed
V381 Cyg with the 60-cm reflector of the Mt. Maidanak Observatory of the
Tashkent Astronomical Institute, 19 BVR measurements were carried out in
September 1991.

The observations are presented in Table 1 and plotted in Figure 1.  The
estimated error of the individual data is about +-0.15 mag.  Light curves in
Figure 1 show that the elements (1) do not need improvement.

It is a pleasure to thank Dr V. S. Shevchenko for the observing time
necessary to carry out the present observations.
