       A NEW DECREASE IN THE LIGHT VARIATION
         AMPLITUDE OF RU CAMELOPARDALIS

     Contrarily to the expectations that RU Cam should
have recovered the old light amplitude during 1968, the
light curve we give shows a decreasing. From these 
photoelectric V observations obtained from November 1967 until
August 1968 at the Merate Observatory we see that after a
quite regular decreasing as far as March, during the
following months some peculiarities in the light variations
occured.

Editor's note: According to Dr. Szeidl's observations
at the Konkoly Observatory the star's regular variation
is now recovering after an irregular phase of several
months (s. also the Proceedings of the IAU Colloquium on
"Non-Periodic Phenomena in Variable Stars" held in Budapest,
1968. Sept. 5-9).
