摘要：

We present the results of narrowband photoelectric observations of comet Hale-Bopp near perihelion, which were made with the AZT-14 telescope at the station Lisniki of Kyiv University Astronomical Observatory. The standard set of IHW cometary filters was used. The total number of cometary observations was more than 500 during the interval March 13-April 29, 1997. The comet's nuclear gas production rates Q of C-2 and C-3 were calculated using the stellar calibration for these filters. The calculations used the Haser model for a neutral cometary atmosphere. The value Af rho, which is characteristic of the dust production rate, was determined too. Mean values of the production rates near perihelion are log Q(C-2) = 28.4; log Q(C-3) = 27.2; (Af rho)(BC) = 6.0.
