Valenti, Universita di Ferrara; M. Turatto and S. Benetti, OAP; M.
T. Botticella and E. Cappellaro, Osservatorio Astronomico di
Capodimonte; and F. Patat, European Southern Observatory (ESO),
report the discovery of a supernova (R = 21.9) on a CCD frame taken
during a search performed with the Max-Planck-Institute 2.2-m
telescope (+ Wide Field Imager) at the ESO on May 13.  SN 2005cq is
located at R.A. = 9h52m00s.48, Decl. = -20o43'26".5 (equinox
2000.0); the supernova and the host galaxy are not visible on
reference images taken with the same equipment in Feb. 2004
(limiting mag R about 24).  A spectrum (range 600-1100 nm,
resolution 0.6 nm), obtained on May 23.46 UT with the ESO 8.2-m
ANTU telescope (+ FORS2), shows 2005cq to be a type-Ia supernova
about 1 week past maximum light, when compared with the spectrum
of SN 1994D (Patat et al. 1996, MNRAS 278, 111) and a redshift of
0.31 is assumed for the parent galaxy.

COMETS C/2005 J11, J12, and K4-K8 (SOHO)
     Following are the initial available positions for additional
presumed comets found on SOHO website images (continuation to IAUC
8549).  All were Kreutz sungrazers except for C/2005 K4 (Meyer
group).  K. Battams writes that C/2005 J11 was diffuse with no tail,
reaching mag about 7.2 at 5.8 solar radii on May 15.243 UT.  C/2005
J12 was tiny with no tail (too faint for photometry).  C/2005 K4
was also tiny and barely above the background, and it showed no
elongation.  C/2005 K5 was very small, 'teardrop'-shaped, and
diffuse, reaching mag about 8.2 at 5.9 solar radii on May 18.701.
C/2005 K6 was very diffuse with no tail and barely above the sky
background.  C/2005 K7 was an extremely faint and diffuse companion
to C/2005 K8, which in turn was diffuse and had a hint of a tail
(reaching mag about 8.2 at 5.6 solar radii on May 20.535).
