2002 JF_56
     L. Barrera, Universidad Metropolitana de Ciencias y Educacion,
Santiago; and C. Tubiana, R. Duffard, and H. Boehnhardt, Max Planck
Institute for Solar System Research, Katlenburg-Lindau, write that
minor planet 2002 JF_56 was observed with the FORS2 instrument at
the European Southern Observatory's 8.2-m Very Large Telescope
telescope 'Antu' on four nights between May 25 and June 2.
Preliminary analysis of the visible spectra indicate an S-type
taxonomy for the object, which is being viewed during a distant
fly-by of the 'New Horizons' spacecraft on June 13.

COMETS C/2006 J9, C/2006 J10, C/2006 J11 (SOHO)
     Three additional Kreutz sungrazing comets have been found on
SOHO website images (cf. IAUC 8720).  C/2006 J9, which was also
found by T. Chen, was stellar and reached mag 7.3 on May 10.579 UT
at 5.9 solar radii.  C/2006 J10 was small and diffuse, reaching mag
7.8 on May 11.204 at 6.0 solar radii.  C/2006 J11 was small,
diffuse, and too faint for photometry.

 C/2006 J9    May 10.564   3 13.6   +16 20   C2     HS   2006-L32

     The Committee on Small Bodies Nomenclature has agreed to name
the comet 1999 RE_70 (cf. IAUC 8704), which has been assigned also
the permanent comet number 176P (MPC 56919), with the same name as
the minor planet (118401):  LINEAR, for the 'Lincoln Laboratory
Near-Earth Asteroid Research' survey that discovered the object (cf.
MPC 56963).

     Further to IAUC 8622, R. Quimby reports the discovery of an
apparent supernova in unfiltered CCD images taken on June 12.41 (at
mag about 16.6), and 13.41 UT (mag about 16.8) using the 0.45-m
ROTSE-IIIb telescope.  SN 2006da is located at R.A. = 23h27m48s.57,
Decl. = +14o28'27".0 (equinox 2000.0), which is 1".5 west and 4".2
south of the center of the apparent host galaxy.  Nothing was
visible at this location in a co-addition of images taken between
2005 July 15 and 2005 Sept. 12 (limiting mag about 18.8).
