SUPERNOVA 2005au IN NGC 5056
     R. Arbour, South Wonston, U.K., reports his discovery of an apparent
supernova (mag approximately 15.8) on unfiltered CCD images taken with a
0.3-m reflector on Mar. 19.955 and 20.817 UT in the course of his
supernova patrol.  The new object is located at R.A. = 13h16m12s.42,
Decl. = +30o56'40".5 (equinox 2000.0), which is 1" east and 21" south
of the center of NGC 5056.  Nothing is visible at this location on
Digitized Sky Survey images from 1989 (limiting red mag 20.9) and 1995
(limiting blue mag 20.8).  Arbour adds that images taken by D. Briggs
(Clanfield, U.K., 0.60-m reflector) on Mar. 20.891 yield position end
figures 12s.38, 42".3 for SN 2005au.
