Abstract
The comet Churyumov-Solodovnikov (1986 IX) was discovered as a result of photographic patrolling of several selected regions near the plane of the ecliptic in the constellations of Sagittarius, Aquarius and Capricornus. Patrolling was carried out with wide-field powerful telescopes of the Fessenkov Astrophysical Institute of the Kazakh Academy of Sciences - on the Kamenskoye Plateau with the 0.5-m meniscus telescopes and at the Coronal'naya Station with the 0.40-m Schmidt telescope. On five plates obtained during July 14–15, 1986 by K.I. Churyumov and V.V. Solodovnikov, we found a new comet designated as 1986i = 1986 IX. The comet was observed in the interval July 14, 1986 – March 25, 1988. On the basis of observations taken over the interval July 14 – Oct. 31, 1994, the authors used the Encke method with due regard of the perturbations of all planets to compute a system of orbital elements. The original orbit of the comet 1986 IX was determined while it was entering the planetary system at a heliocentric distancer = 50.132 A.U.: Epoch = 1957 Aug. 4.0 TT,T = 1986 Apr. 25.98119 TT,e = 0.999120,q = 2.63337 A.U.,ω = 157.79532°, Ώ = 133.85082°,i = 114.70008°. The elliptical elements of the original orbit show that the comet comes from the nearest region of the Oort Cloud, located at the heliocentric distance near 3000 A.U.
