       ON THE SMALL LIGHT FLUCTUATIONS OF RU CAM


Here is the preliminary photoelectric V light curve obtained with the 40"
reflector from December 1966 until July 1967.

                        [FIGURE 1]

The amplitude increases progressively from about 0.^m05 in January to 0.^m18 in
April. Thenceforward it decreases to 0.^m14 and again in the two successive
cycles it attains 0.^m21. In July the amplitude is 0.^m03 smaller. Also the
period and the mean brightness of RU Cam in the different cycles show small
fluctuations during the interval of these observations.
