V616 Mon = A0620-00 is a prototype of black hole transient X-ray binaries.\nOur 2003-16 optical photometry of the object during X-ray quiescence, obtained\nby 50-250 cm telescopes in Crimea, Caucasus Mountains and Slovakia, consists of\n~ 7660 CCD frames in Johnson-Cousins $V,R,R_C,I$ bands and the integral light.\nDuring 2003, 2008-9 and 2015-16 passive states, the phase light curve of the\nbinary exhibited mainly variations caused by an ellipsoidal shape of the red\ndwarf component.
