Comet C/2008 J1 (BOATTINI)

Discovery: IAUC 8940

  A. Boattini reports his discovery of a 14th magnitude comet with a coma diameter of about 50" and a fan-shaped tail 2' long in p.a. 235 deg on Catalina Sky Survey CCD images obtained with the 0.68-m Schmidt telescope on 2008 may 2.46 UT.  Following posting on the Minor Planet Center's 'NEOCP' webpage, several other CCD astrometrists have found this object to show cometary appearance.  S. Nakano, Sumoto, Japan, reports that images obtained on May 2.73-2.74 UT by A. Asami and T. Sakamoto (Bisei Spaceguard Center 1.0-m f/3 reflector) show a coma diameter of 20" and a tail 24" long in p.a. 230 deg.  R. Apitzsch (Wildberg, Germany, 0.35-m f/4.2 reflector, May 3.02-3.03) finds a 1' tail toward the southwest.  V. Gonano, E. Guido, and G. Sostero (Remanzacco, Italy, 0.45-m f/4.4 reflector) report that thirty stacked 60-s unfiltered exposures obtained during May 3.02-3.05 show a compact coma about 15" in diameter (total mag about 14.7) with a central condensation and an apparent tail 35" long in p.a. 280 deg.  R. Ligustri (Talmassons, Udine, Italy, 0.35-m f/5 reflector, May 3.08-3.09) writes that thirty 60-s exposures show a faint tail 45" long.  J. M. Aymami (Tiana, Spain, 0.25-m f/5 reflector, May 3.11-3.12) finds a nuclear condensation and a short, fan-like tail approximately 16" long in p.a. 238 deg. See also MPEC 2008-J17
