SUPERNOVA 2005cl IN MCG -01-53-20

Further to IAUC 8542, H. Pugh and W. Li report the LOSS
discovery of an apparent supernova on unfiltered KAIT images taken
on June 12.48 (at mag 18.3) and 14.45 UT (mag 18.2).  An image
taken on June 2.47 also showed a marginal detection of the new
object (limiting mag about 18.8).  SN 2005cl is located at R.A. =
21h02m02s.35, Decl. = -6o17'35".7 (equinox 2000.0), which is 18".0
west and 13".3 north of the nucleus of MCG -01-53-20.  KAIT images
taken on May 12.50 (limiting mag about 19.5) and 23.49 (limiting
mag about 19.0) showed nothing at this position.
