  THE LIGHT CURVE OF RU CAMELOPARDALIS DURING THE PERIOD
            OCTOBER 1969 - AUGUST 1970


      These V observations continue the series of photoelectric 
measures obtained at Merate during the period December 
1966 - July 1967 (Merate Contr. 318) and November
1967 - August 1968 (Mem. Soc. Astron. Ital. 39, 533, 1968).

                    [FIGURE 1]

      After the recovering of its periodic variation in
September 1968 and the subsequent progressive amplitude 
reduction with the minimum in April, May, 1969 (B. Szeidl,
Commission 27 Circular No 385) we see that the cyclical variation 
of the light amplitude continues. It reaches its
maximum in October 1969, afterwards it decreases again to
the minimum during the late summer 1970.
