Scientific paper

We present new observations of 19 symbiotic and symbiotic-like stars. Photoelectric UBV(R) observations cover the 1993.75 to 1994.75 period. The main results can be summarized as follows: Z And: the visual light curve (LC) indicates a quiet stage of the star. EG And: The primary minimum at JD 2 449 230 was observed. V 1413 Aql: The recent outburst has probably finished. UV Aur: Historical photographic LC from December 1895 to March 1963 is presented. It suggests changes in the periodicity of the brightness variation being approximately between 395 and 360 days. TX CVn: A slow gradual decrease in the star's brightness is observed. Historical photographic LC from May 1906 to March 1992 is presented. It indicates an increase in the activity approximately at JD 2434000. T CrB: Observations indicate a decrease of brightness mainly in U. BF Cyg: The star has returned to quiescence. Historical photographic LC from October 1896 to September 1992 is presented.
