(134340) PLUTO, (136199) ERIS, AND (136199) ERIS I (DYSNOMIA)
The following announcement appeared in IAUC 8747:

Following the Aug. 24 resolution by the International Astronomical Union 
to the effect that the Solar System contains eight "planets" 
(Mercury-Neptune), with (1) Ceres, Pluto, and 2003 UB_313 to be 
considered representative "dwarf planets", the Minor Planet Center 
included Pluto and 2003 UB_313 (along with two other new potential
dwarf-planet candidates) in the standard catalogue of numbered objects 
with well-determined orbits as (134340) and (136199), respectively.

Following near-unanimous acceptance by both the Committee
on Small-Body Nomenclature and the Working Group on Planetary-System 
Nomenclature (in consultation with the discovery team), the IAU 
Executive Committee has now approved the names Eris for (136199) and 
Dysnomia for its satellite (136199) Eris I [formerly S/2005 (2003 
UB_313) 1; cf. IAUC 8610].

Editor: Informal names for 2003 UB 313 as Xena and its satellite as 
Gabrielle, are now also superseded.

SUPERNOVA 2006ev IN UGC 11758
Discovery by Michel Ory, Switzerland of a possible supernova (IAUC 
8747):
SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2006ev  Sep. 12.9   21 30 59.26  +13 59 21.2  16.6   23"  E, 11" N

SUPERNOVAE 2006ew-2006fc
These designations relate to discoveries by astronomers working on the 
Sloan Sky Digital Survey II collaboration. Each object is fainter than 
magnitude 20. SN 2006ew to 2006fb were recorded on August 27 and 2006fc 
on September 11 according to CBET 621.
