This false-color image was taken by Hermann Mikuz on 2003 May 25.925 UT, using a 0.60-m f/3.3 Deltagraph telescope. Mikuz used a V filter and the exposure time was 90 seconds. Discovery During an unsuccessful attempt to recover the asteroid 1953 GC, George van Biesbroeck (Yerkes Observatory, Wisconsin, USA) discovered this comet on a 16-minute exposure obtained with the 24-inch reflector on 1954 September 1.18. He estimated the magnitude as 14.5, and described the comet as round, well condensed, and 8 arc seconds across. The comet was also present on a 16-minute exposure obtained with the same telescope on September 1.19. Historical Highlights
