Circular No. 8217 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION New Satellite of Uranus S/2003 U3 A new candidate (R = 25.1-25.3) for an outer satellite of Uranus was discovered by S. S. Sheppard, University of Hawaii, on images obtained by D. C. Jewitt and himself on Aug. 29 and 30 with the Subaru 8.2-m reflector at Mauna Kea. After they had also observed the object with the Gemini 8.2-m reflector on Sept. 20, B. G. Marsden tentatively identified the object with a satellite candidate observed by M. Holman and J. Kavelaars on the single night of 2001 Aug. 13 with the 4-m Blanco reflector at Cerro Tololo (cf. IAUC 7980, 8213, 8216), a result confirmed by Kavelaars' recognition and measurement yesterday of a 2001 Aug. 25 image with the Canada-France-Hawaii telescope. Full astrometry, Marsden's orbital elements (a = 0.098 AU, e = 0.78, i = 51 deg, H = 12.7), and an ephemeris appear on MPEC 2003-T58. (C) Copyright 2003 CBAT 2003 October 9 (8217) Daniel W. E. Green
