Scientific paper

We collected 804 observations made during 13 apparitions of the comet in 1906 - -- 1991. Applying the Marsden's method for nongravitational effects, but with four parameters A, eta, I, phi connected with the rotating nucleus of the comet, we also took into consideration an asymmetric activity of the comet with respect to perihelion. The maximum value of the known function g(r) was shifted by tau from the perihelion instant, using in equations of the comet's motion a value of g(r') for r'=r(t-tau). To take into account the spin-axis precession of the comet's nucleus, and also the fact that in the observation interval of the comet a change of sign of tau was found, we have determined values of the constant daily changes for I, phi and tau. Finally, to construct the numerical model for the comet's motion, we found ten nongravitational parameters along with six orbital elements by the least squares correction. Thus, we were able to link successfully all the observations of the comet with the mean residual RMS equal to 1.56 arcs.
