SUPERNOVAE 2005ex-2005gj AND 2005go-2005gy
     CBETs 247 and 254 contains discovery information (astrometry,
photometry, redshifts, spectroscopic classifications) for 50 new
supernovae discovered in September and early October in the course
of the Sloan Digital Sky Survey II and communicated by J. Frieman
(Fermilab and University of Chicago).  All the objects are now
apparently fainter than red mag 19 except 2005gj, a probable type-
IIn supernova that may currently be near mag 18.  SN 2005fk is a
type-Ib/c hypernova, SN 2005gi is a type-II supernova, and the rest
apparently are of type Ia.


SUPERNOVAE 2005gm, 2005gn, 2005gz, 2005ha, 2005hb
     Five apparent supernovae have been discovered on unfiltered
CCD frames:  2005gm by P. Luckas, O. Trondal, and M. Schwartz (cf.
IAUC 8575) with the 0.35-m telescope at Perth, and the rest by R. R.
Prasad, K. Shimasaki, E. Lee, and W. Li (LOSS/KAIT; cf. IAUC 8611).

COMET C/2005 Q6 (SOHO)
     Further to IAUC 8615, K. Battams reports measurements for a
very faint comet (with a slightly irregular shape) that does not
belong to any known group, found on SOHO website images.
