(136472) MAKEMAKE
     The IAU's Committee on Small Body Nomenclature and Working
Group for Planetary System Nomenclature have agreed to give to the
transneptunian dwarf planet, or 'plutoid, (136472) 2005 FY_9 (cf.
IAUC 8577) the name "Makemake", as announced on MPC 63395.


2008 KV_42
     An asteroidal object (mag r = 23.7-23.8) discovered by B.
Gladman, J. Kavelaars, and J.-M. Petit on CCD images obtained on
May 31 with the 3.5-m Canada-France-Hawaii telescope (and confirmed
via observations made at Cerro Tololo and Mt. Hopkins through July
8) has a retrograde orbit (i = 103 deg) with q about 20 AU, Q about
72 AU, and T about 2034 (currently r = 32 AU).  Details are given
on MPEC} 2008-O02.


COMETS C/2008 H2-H5 (SOHO)
     Further to IAUC 8957, additional apparent comets have been
found on SOHO website images; all are Kreutz sungrazers except for
C/2008 H4 (Meyer group), which was small and elongated but not
diffuse (mag about 7.5).  C/2008 H2 was stellar in appearance and
very faint (mag about 8) but very long-lasting in the SOHO images.
C/2008 H3 was teardrop-shaped and quite bright (mag about 6) in C2
images.  C/2008 H5 was small with a short tail (mag about 6.5) in
C2 images.

COMET P/2008 L2 (HILL)
     The following improved orbital elements from MPC 63377 show
this comet (cf. IAUC 8953) to be of short period.
