               OCTOBER 1971-APRIL 1972

During the period from October 1971 to April 1972 photoelectric 
UBV observations of the variable star Pleione (BU Tau)
were obtained at the Crimea Station of the Sternberg Astronomical 
Institute. The star showed considerable brightness variations 
(s. Figure). On March 18-20 its brightness decreased to

                   [FIGURE 1]


B=5.5m, below the minimum of 1938. On March 15 an increase of
brightness of about 0.5m was observed. The brightness variations 
were accompanied with color variations. During the 
decrease of brightness the color B-V became more positive and
the color U-B more negative. Apparently variations in the
star's envelope are in progress again, therefore photometric
and especially spectral observations are very desirable.
The results of our observations will be published in detail
in the Soviet Bulletin "The Variable Stars".
