[39.13] Visible and IR observations of the outer solar system object 29981 (1999 TD10)

B.E.A. Mueller (NOAO), C.W. Hergenrother (LPL, Univ. of Arizona), N.H. Samarasinha (NOAO), H. Campins (Univ. of Central Florida), D.W. McCarthy, Jr. (Steward Obs., Univ. of Arizona)

\noindent We observed the outer solar sytem object 29981 (1999 TD10) in the visible (R) for 5 nights in September 2001 and for 3 nights in October 2002. We have simultaneous IR observations in J and H for 2 nights in September 2001. The visible colors are consistent with those by Consolmagno et al.\/ (2000). We also derived IR colors. We will present our detailed analysis of our photometry and will discuss the rotational period derived. Our results are not in agreement with the presence of activity claimed by Choi et al.\/ (2003).
