SUPERNOVA 2005cv IN UGC 1359
     Further to IAUC 8557, D. R. Madison and W. Li report the LOSS
discovery of an apparent supernova (mag 17.6) on unfiltered KAIT
images taken on July 10.49 and 11.47 UT.  SN 2005cv is located at
R.A. = 1h53m42s.56, Decl. = +29o56'04".3 (equinox 2000.0), which is
4".1 east and 4".6 north of the nucleus of UGC 1359.  A KAIT image
taken on Jan. 21.19 showed nothing at this position (limiting mag
about 19.5).

1994 XD
     Further to IAUC 8329, L. A. M. Benner, M. C. Nolan, S. J.
Ostro, J. D. Giorgini, J. L. Margot (now at Cornell University),
and C. Magri report that Arecibo delay-Doppler images (2380 MHz,
12.6 cm), obtained on June 24-25, reveal that 1994 XD is a binary
system.  Preliminary estimates, based on range extents at 150-m
resolution, give the primary's diameter as about 600 m and a lower
bound on the secondary's diameter as 150 m (apparent separation
about 600 m on June 24, with uncertainty as much as 300 m).

COMETS C/2005 K9, 2005 K10, 2005 L5, 2005 L6 (SOHO)
     Following are the initial available positions for additional
presumed comets found on SOHO website images (continuation to IAUC
8551).  All were Kreutz sungrazers except for C/2005 K9 (Meyer
group).  K. Battams writes that C/2005 K9 appeared stellar,
reaching mag about 7.9 at 6.0 solar radii on May 28.189 UT.  C/2005
K10 was very diffuse and had a very faint tail that was 150" long
at 6.6 solar radii on May 30.481.  C/2005 L5 and C/2005 L6 were
both faint and diffuse with no tail (C/2005 L5 also decribed as
small).  C/2005 L6 was found independently by S. Hoenig.

     E. J. Christensen reports that CCD images taken with the 0.5-m
Uppsala Schmidt telescope on July 5.57-5.69 UT show a moderately
diffuse asymmetric coma (long axis 10", short axis 6"), elongated
toward p.a. 260 deg.
