SUPERNOVA 2005au IN NGC 5056
An e-mail was received from Ron Arbour of South Wonston, England on 2005 
March 19 reporting a possible supernova in NGC 5056.
Subsequently the Central Bureau issued an Electronic Telegram 125 
reporting this discovery of an object of approximately magnitude 15.8 on 
unfiltered CCD images taken with a 0.3-m reflector on 2005 Mar. 
19.9554UT and 20.817 UT (limiting magnitude 17.5) during the course of 
the UK Nova/Supernova patrol.  The new object is located at:
RA 13h 16m 12.42s  DEC +30 56' 40.5" (2000), which is 1" east
and 20.8" south of the centre of NGC 5056.

Nothing is visible at this location on Digitised Sky Survey images from 
1989 (limiting red mag 20.9) and 1995 (limiting blue mag 20.8).  Ron 
adds that images taken by David Briggs (Clanfield, England, 0.60-m 
reflector) on Mar. 20.891 yield position end figures 12.38s, 42.3" for 
the object.

The designation SN 2005au has been allocated and subsequently announced 
on IAUC 8496. Congratulations to Ron on the discovery of his 16th 
supernova.
