Scientific paper

We present new observations of 10 symbiotic and symbiotic-like stars. The photoelectric UBV(R) observations cover the period 1994.75 to 1996.0. The CCD VRI, photographic and visual data also cover earlier times. The main results can be summarized as follows: (1) CQ Dra: The expected sudden brightening in the U color has been observed around JD 2 449 700. After then, the star's brightness declined smoothly in all three colors. (2) YY Her: The steady decline of the star's brightness in the V and R colors has been observed. (3) V443 Her: Variability with an amplitude of about 0.4 mag in the V color has been detected, while nothing similar has been found in the R and I. (4) AX Per: Our present data cover in part the primary minimum of the star. During the autumn of 1995, a small increase in all three colors has been observed. (5) PU Vul: A brightness minimum at JD 2 449 953, best pronounced in the V color, has been observed.
