Positions and orbit of comet 21P/Giacobini-Zinner from observations in Tajikistan
Abstract
Quasisynchronous astrometric observations of short-period comet 21P/Giacobini-Zinner were carried out at the Sanglokh International Astronomical Observatory (IAOS) and the Gissar Astronomical Observatory (GisAO) of the Institute of Astrophysics of the Academy of Sciences of the Republic of Tajikistan, in 2018. The coordinates of comet were determined and the orbit was calculated. The results of observations in IAOS and GisAO are in satisfactory agreement with each other, as well as with available observations. The conclusion is made about the stability of the comet orbit during observation. Based on a talk presented at the XI International Conference "Near-Earth Astronomy and Space Heritage" (Sep 30 - Oct 4, 2019, Kazan, Russia).
