Scientific paper

The results of four colour photometric observations of SN 1987A made by the Bolivian expedition of the Pulkovo Observatory and the Main Astronomical Observatory of the Ukrainian Academy of Sciences from May 15 to October 20, 1987 are presented. The constant of the exponential brightness decline of SN in the V band is determined. It attains 114d±2d, which is in good agreement with the period of the radioactive decay of 56Co.
