An analysis of the 2796 visual observations as well as of 282 V, B or U photoelectric observations was carried out using a two-parametric model for the light curve of the comet. After having applied an aperture correction to the visual observations, the following photometric parameters were derived: before perihelion n = 2.5, after perihelion n = 3.6 and a drop of m0 by 1.5 -1.9 after the perihelion passage. From the UBV photoelectric data the coma was found to be more gaseous before the perihelion passage.
