This image was obtained with the 48-inch Oschin Schmidt Telescope at Palomar Observatory (California, USA) on 1992 April 27.31. The comet trailed during the exposure of the Kodak IIIaF (red) plate, but still shows a trace of tail toward the lower right. This image was obtained through SkyMorph at the Goddard Space Flight Center. Discovery A 90-minute IIIa-J exposure was obtained by Jean Mueller and C. Brewer (Palomar Observatory, California, USA) with the 1.2-m Oschin Schmidt telescope on 1992 April 9.35. Upon examining the plate a couple of days later, Mueller found the faint trail of a possible comet. She estimated the magnitude as 17.5 and noted a "possible hint of a tail to the west." She noted a 30-minute exposure was obtained of the same region with the same telescope on April 11.40 and she was able to locate a trail that was too weak to confirm whether it was a comet or a minor planet.
