N1 - Funding Information:
It is a pleasure to thank Drs Michael J.S. Belton and Tod R. Lauer for help with acquiring the data. We are very grateful to Drs Stephen Tegler and Philippe Rousselot for providing their data in electronic form. This work was supported by Planetary Astronomy Grants from NASA for B.E.A.M., N.H.S., and H.C., and by an NSF Grant for H.C.

N2 - The outer Solar System object (29981) 1999 TD10 was observed simultaneously in the R, and J and H bands in September 2001, and in B, V, R, and I in October 2002. We derive B-V=0.80 ±0.05 mag, V-R=0.48±0.05 mag, R-I=0.44±0.05 mag, R-J=1.24±0.05 mag, and J-H=0.61±0.07 mag. Combining our data with the data from Rousselot et al. (2003, Astron. Astrophys. 407, 1139) we derive a synodic period of 15.382±0.001 hr in agreement with the period from Rousselot et al. Our observations at the same time, with better S/N and seeing, show no evidence of a coma, contrary to the claim by Choi et al. (2003, Icarus 165, 101).
