S. Sheppard, University of Hawaii (UH), reports the discovery of seven new satellites of Jupiter, with the astrometry, orbital elements, and ephemerides given on MPEC 2003-E11. CCD observations were obtained during Feb. 5-Mar. 4 by Sheppard, D. C. Jewitt, J. Kleyna, Y. R. Fernandez, and H. H. Hsieh at Mauna Kea with the 8.3-m Subaru telescope, the 3.6-m Canada-France-Hawaii Telescope, and the 2.2-m UH telescope. The very preliminary orbital elements by B. G. Marsden indicate that two objects have direct orbits and five have retrograde orbits: S/2003 J 1, e = 0.79, i = 35 deg, P = 236 days; S/2003 J 2, e = 0.38, i = 152 deg, P = 983 days; S/2003 J 3, e = 0.24, i = 144 deg, P = 505 days; S/2003 J 4, e = 0.20, i = 145 deg, P = 722 days; S/2003 J 5, e = 0.21, i = 165 deg, P = 761 days; S/2003 J 6, e = 0.76, i = 22 deg, P = 234 days; S/2003 J 7, e = 0.41, i = 159 deg, P = 747 days. Absolute magnitudes range from 15.6 to 16.9. (C) Copyright 2003 CBAT 2003 March 4 (8087) Daniel W. E. Green
