Abstrakt
We present new multicolour (UBVRCIC) photometric observations of classical symbiotic stars, EG And, Z And, BF Cyg, CH Cyg, CI Cyg, V1329 Cyg, TX CVn, AG Dra, Draco C1, AG Peg, and AX Per, carried out between 2007.1 and 2011.9. The aim of this paper is to present new data of our monitoring programme, to describe the main features of their light curves (LC) and to point problems for their future investigation.
The data were obtained by the method of the classical photoelectric and CCD photometry ((c) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
