Type: Periodic Perihelion date: 13 June 2024 Perihelion distance (q): 1.6 Aphelion distance (Q) : 8.0 Period (years): 10.5 Eccentricity (e): 0.68 Inclination (i): 17.6 JPL orbit diagram COBS lightcurve Atlas Howard J. Brewington (Cloudcroft, New Mexico, USA) discovered this comet with his 40-cm reflector on 28 August 1992. He gave the magnitude as 10 and described the comet as "very small and diffuse." A. Sugie (Dynic Astronomical Observatory) confirmed the discovery on using a 25-cm Schmidt. He estimated the magnitude as 13 and described the comet as very faint and diffuse. The comet was recovered by Fernanda Artigue, Herbert Cucurullo, and Gonzalo Tancredi (Molinos Astronomical Observatory, Montevideo, Uruguay) on 26 August 2002, in the course of the Búsqueda Uruguaya de Supernovas, Cometas y Asteroides (BUSCA) project. They were using a 46-cm telescope and a CCD camera. The comet was described as a centrally condensed, diffuse coma about 20 arc seconds across. A confirmation by the BUSCA group on August 27.98 also indicated the magnitude was 16.8. The comet was expected to reach a maximum magnitude of 10.5 at the 2003 apparition, but visual observers at the end of February and beginning of March reported magnitudes within the range of 11.5 to 12.5. The comet remained small and weakly condensed throughout the apparition.
