	  PHOTOELECTRIC OBSERVATIONS OF V375 Cas


 The eclipsing binary V375 Cas, BD+62d2332, was observed photoelectrically
with the 60 cm telescope at Beijing Astronomical Observatory in August -
November 1982.
 A total of 604 photoelectric BV observations were obtained on 8 nights. The
coordinates of the comparison star and check star are given in Table I.

  All the observations were corrected for differential extinction and 
transferred to UBV system. The times of minimum light determined with the Kwee 
and Van Woerden's method are given in Table II.

               BV light curves of V375 Cas in 1982.

 Using the above new photoelectric minima together with the photographic
minima given by Chuprina (1959), Grigoriskij (1959), Satanova (1960) and
Kukarkin and Novikov (1960), the new ephemeris has been derived by the
weighted least squares as follows

   JD Hel. Min I = 2445635.1514 + 1.47338191d E
		        +-.0016  +-.00000028

   The B, V light curves are given in Figure 1.

 The light curve of V375 Cas is similar to that of AW  ac (Jiang et al.,
1983). A complete analysis of the light curves of V375 Cas will be presented
elsewhere.
