SNe 2002ep and 2002eq were reported by W. M. Wood-Vasey et al. from Palomar NEAT images (cf. IAUC 7953), while the remaining three objects were found on LOTOSS KAIT images (W. D. Li, B. Swift, and M. Ganeshalingam; cf. IAUC 7906). SN 2002 UT R.A. (2000.0) Decl. Mag.

Buie, Lowell Observatory; D. Cruikshank, Ames Research Center, NASA; S. Tegler, Northern Arizona University; and W. Romanishin, University of Oklahoma, report on confirming observations of the binary transneptunian object 1997 CQ_29 (cf. IAUC 7824), obtained with the Hubble Space Telescope during June 18.312-18.351, 30.131-30.170, and July 12.152-12.191 UT: "On each date, three 800-s exposures were obtained with the F814W filter (roughly I band), the target being placed on the PC chip (0".045 pixel scale) of the WFPC2 camera. The binary was easily detected on all three dates with a signal-to-noise ratio of 25 or more for each component. The components were separated by an average of 0".334 (approximately 8 pixels). The position angle measured from component A to component B was seen to change slowly from 334 +/- 1 deg on June 18 to 340.7 +/- 0.8 deg on July 12, confirming orbital motion."
