         OBSERVATIONS OF SOME VARIABLE STARS


 During the period June 1965 - August 1970 56 blue plates (Zenith 
Astronomical and Scientia 67 A 50) have been taken with the 135 mm astrograph on
the field centered at RA = 20h13m; D = +47d (1950). The results of 
observations of some variable stars in this field are given in this paper.
XX Cyg - Four maxima of this RRs star were observed on:


    JD       m       O - C

  961.396   11.1   - .001
40124.346   11.3   + .007
  152.247   11.4   - .008


         The phases have been obtained with the elements of the General
         Catalogue. The star varied between 11.3 and 12.5 magn.

BW Cyg - Semiregular variable. During the period of observation this star
         varied between 13.0 and 14.2 magn. The observations are satisfied
         by the following elements: max = 2438941+ 173d.
         The epochs of maximum are:

    JD       m     O - C

40504       13.4   + 6

BX Cyg - Probably an irregular variable star (12.8-14.1 magn. in our plates).
       The epochs of maximum are:

     JD    m        JD       m
2438940   13.1   2439680    13.0
  39023   12.9     40415    13.0
  39350   13.0

CN Cyg - Mira star. Only two maxima have been observed on: JD 2439026
      (8.4) and 2440955 (8.6) in accord with the elements of the General
      Catalogue.

V 786 Cyg   - Irregular variable star with a marked red colour. This star
          had nearly constant brightness most of the time and showed some
          rapid variations of 0.5m-0.6m with a cycle length of two to five days.

UU Cep - No maxima of this semiregular variable have been observed. The
            fitting of the light curves suggests the following new improved
            elements:
            max = 2440768+ 372.7d.
HI Cep - Eclipsing variable with unknown elements. The observations near the
            minima give:

                  JD       m

               24...

              38935.415   13.7
              40150.249   13.0
              40504.273   13.5

      The star varies between 12.0 and 13.7 mpg.

GR 306 - This new suspected variable star has been discovered on 63 films
      (Tri X + GG 14) taken with two Schmidt telescopes 25/30/75 cm in
      Pegasus.

                              [FIGURE 1]

Its position is RA = 22h07m26s; D = +32d20.5' (1950.0). Very likely this star
belongs to the RR Lyrae type. The photovisual range is 13.6 - 14.1. No
elements have been derived. The finding chart is shown in Figure 1.

 Erratum: In IBVS No. 2161 (1982 June 15), the new variable star is not
 GR 306 but GR 310.
