This object was reported as a potential comet by A. Fitzsimmons (T05), whodescribed it as having a 8"-10" coma in stacked images taken on Dec. 8. Inimages obtained with the CFHT (568) on Dec. 9, R. Weryk reported that objecthad a FWHM of 1".3 (compared to 0".77 +/- 0".03 for nearby stars) and anobvious ~10" tail extending almost directly south. K. Sarneczky (K88) reportedthat six stacked 120s exposures on Dec. 10.9 UTC showed a strongly-condensed6" coma and a 10" tail in P.A.. 180. R. Furgoni (K51) reported a very faintcoma and a hint of a 15" tail in P.A. 180 on Dec. 11.8 UCT. H. Sato (Q11)reported a strongly-condensed 9" coma and a 11" tail in P.A. 183 on tenstacked 60s exposures on Dec. 13.6 UTC. L. Buzzi (204, Dec. 15.0 UTC)reported a compact 10" coma and a broad ~13" tail centered in P.A. 177.
