Comet Grigg-Skjellerup on July 10, 1992
10 July 1992: This photo shows Comet Grigg-Skjellerup, as imaged by the ESO 3.6 m telescope at the La Silla Observatory in the early morning of July 10, 1992, just 15 hours before the Giotto encounter with this comet. The observation was made by Dr. Klaus Jockers from the Max-Planck-Institut für Aeronomie (Katlenburg-Lindau, Germany), and in the course of a special monitoring programme in support of the Giotto Extended Mission. The digital image was transmitted to the ESO Headquarters in Garching via the permanent satellite link, immediately following the observations. The photo is a composite of four one-minute red-sensitive exposures. The other objects in the field are galactic stars.
