摘要：
We present the UBV observations of FG Sge performed on 55 nights in 1996-1997 with three apertures: 27 ", 13 ".5, and 10 ". We measured the star together with part of the surrounding planetary nebula He 1-5 through the smaller apertures and the sum of three components-star + companion + nebula-through the large aperture. In 1996 the deepest minimum of all the five minima that had occurred since 1992, when the star entered the R CrB phase, was observed.
