SATELLITES OF JUPITER
     S. 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.
