Scientific paper

Results are presented from photometric observations of V1057 Cyg made during 1976-1988. An unexpected end to the fading of the star's brightness in the optical and IR spectral regions is observed. However, the optical brightness of V1057 Cyg is still about 2 m higher than the preoutburst level. It is shown that two dust condensation episodes from local matter occurred during the postmaximum evolution of V1057 Cyg.
