      HD 216711, PROBABLY AN ECLIPSING VARIABLE

Photoelectric measurements were made in a field in
Cepheus during September and October 1969 with the 61 cm
telescope of the Lund Observatory. HD 216711 was one of the
standard stars used. In the night of 1969, October 5-8
(JD 2440500.3 - 2440500.7) the magnitude variation shown
in the Figure was recorded. The variation in B-V and U-B is

less than 0.01m. HD 216711 is of spectral type B1  (Jaschek,
Conde and de Sierra, 1964) and its magnitude and colours
are given by Hiltner (1956) as V = 9.05, B-V = +0.62,
U-B = -0.33.
      The mean error of one measurement is less than
0.02m. The star was also observed in the following intervals:

     JD 2440478.306 - .628
        2440479.424 - .527
        2440481.292 - .354
        2440482.285 - .619
        2440504.343
        2440506.410 - .598

      No variation was recorded in these intervals.
