Abstract:
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 cover also earlier times. The main results
can be summarized as follows: CQ Dra: The expected sudden brightening in the
U colour has been observed around JD 2,449,700. After then, the star's
brightness has declined smoothly in all three colours. YY Her: The steady
decline of the star's brightness in the V and R colours has been observed.
V443 Her: Variability with an amplitude of about 0.4 mag in the V colour has
been detected, while nothing similar has been found in the R and I. AX Per: Our
present data cover in part the primary mimimum of the star. During the autumn
of 1995, a small increase in all three colours has been observed. PU Vul:
A brightness minimum at JD 2,449,953, best pronounced in the V colour, has
been observed.
