title: Multicolor electrophotometry of the peculiar object V1357 Cyg=Cyg X-1 in the period 1986 -- 1992
abstract: \rm Observations of close binary system (CBS) V1357 Cyg=Cyg X-1 in the $WBVR$ bands are reported. Photometry was carried out at the telescopes located in Kazakhstan, Uzbekistan and Crimea equipped with single-channel $WBVR$-photometer with photon counting. 1358 individual observations in $WBVR$ bands on 202 nights were obtained. The analysis of the photometric data allows to conclude that different photometric effects are superimposed on the orbital light curve of the system. Among them are brig
