SATELLITES OF JUPITER AND SATURN
     Further to IAUC 8502 and 8730, the IAU Working Group for
Planetary System Nomenclature (WGPSN) has approved the following
new designations and names of satellites of Jupiter and Saturn:

    Jupiter XLIX    Kore        = S/2003 J 14

    Saturn XXXVI    Aegir       = S/2004 S 10
    Saturn XXXVII   Bebhionn    = S/2004 S 11
    Saturn XXXVIII  Bergelmir   = S/2004 S 15
    Saturn XXXIX    Bestla      = S/2004 S 18
    Saturn XL       Farbauti    = S/2004 S 9
    Saturn XLI      Fenrir      = S/2004 S 16
    Saturn XLII     Fornjot     = S/2004 S 8
    Saturn XLIII    Hati        = S/2004 S 14
    Saturn XLIV     Hyrokkin    = S/2004 S 19
    Saturn XLV      Kari        = S/2006 S 2
    Saturn XLVI     Loge        = S/2006 S 5
    Saturn XLVII    Skoll       = S/2006 S 8
    Saturn XLVIII   Surtur      = S/2006 S 7


RING OF URANUS
     The IAU WGPSN has recently designated the Uranian ring 1986 U
2R (cf. IAUC 8373; Stone and Miner 1986, Science 233, 39) the "zeta
ring".


2006 VV_2
     L. A. M. Benner, S. J. Ostro, and J. D. Giorgini, Jet
Propulsion Laboratory (JPL), California Institute of Technology
(CIT); M. W. Busch, CIT; R. Rose, M. A. Slade, and R. F. Jurgens,
JPL/CIT; M. C. Nolan and A. A. Hine, Arecibo Observatory; G. J.
Black, University of Virginia; and L. M. Carter, Smithsonian
Institution, report that Goldstone (8560 MHz, 3.5 cm) and Arecibo
(2380 MHz, 12.6 cm) radar observations during Mar. 27-Apr. 3 reveal
that the minor planet 2006 VV_2 (cf. MPEC 2006-V47, 2006-W87),
which passed only 0.0226 AU from the earth around Mar. 31.25 UT
(with computed V = 10.0) and has H = 16.7 (MPO 118180), is a binary
system.  Preliminary estimates for the component diameters are 1.8
and > 0.3 km.  The maximum orbital distance between the components
is at least 1.5 km.
