254P/2010 T1 (McNaught)
Abstract
M. Meyer, Limburg, Germany, has identified observations of comet P/2010 T1 (cf. IAUC 9172) on NEAT images obtained at Palomar on 2001 Oct. 23.5 (when the comet was slightly diffuse) and Dec. 18.4 UT, as well as a single trail on a Digitized Sky Survey image obtained with the 1.2-m Schmidt telescope at Siding Spring on 1980 Oct. 5; the identity of the astrometry (published on MPC 76729) was confirmed by S. Nakano (Sumoto, Japan) and by G. V. Williams (Minor Planet Center), leading to the assignment of the permanent number 254P to this comet. Orbital elements by Nakano suggest T = 1980 Sept. 25.59, 1990 Oct. 15.69, 2000 Oct. 9.30, and 2010 Oct. 26.64 TT. 1980 UT R.A. (2000) Decl. Mag.
