New Jupiter Satellite S/2003 J 23
     Further to IAUC 8276, the discovery of a new satellite of
Jupiter has been reported on CCD images taken with three telescopes
at Mauna Kea by a team led by S. S. Sheppard.  Astrometry,
preliminary orbital elements by B. G. Marsden, and an ephemeris
appear on MPEC 2004-B81 (e = 0.31, i = 149 deg, P = 759 days, H =
16.7).

The discoveries of small outer satellites far from Jupiter depends on the size of the telescopes. The last ones of fainter satellites were made by accident with large field telescopes searching for comets or asteroids.
