Photographic observations of the Giacobini-Zinner comet at the Zvenigorod Observatory

This article presents an archive of photographic plates scans obtained from the observations of comet 21P/Giacobini-Zinner in the period from 08/14/1985 to 10/18/1985 on the “Zeiss-400/2000” astrograph. The obtained photographic plates (41) were scanned and published on the Institute of astronomy RAS (INASAN) web-site as an open access archive. Images of sufficient exposure time and quality to study the details of the structure of the comet are selected. The spatial dimensions of the coma are estimated. A series of selected images will provide a basis for a more detailed research of the comet.
