A new bright transient x-ray source was discovered by WATCH instrument on board GRANAT spacecraft on January 8, 1991. Maximum flux from the newly discovered source was 2 Crab units in 8-20 keV spectral band. During January 16-21 WATCH detected the dip in the light curve of the x-ray Nova. On January 16, 1991 the flux decreased to half that of the Crab. In five days the source became brighter again. Light curves in two energy bands are presented.
