M33 - Attempted Observation of Extragalactic Nova : M33 2006 1

M33 part (Triangulum)
An extragalactic nova was discovered in M33 on 2006/09/28.20 
by University of Texas & Koichi Itagaki (CBET 655)
having a magnitude of +16.5 
(Extragalactic Novae page at Rochester Supernova site | Discovery Image 1 | Discovery Image 2)

Image below (2006-10-05.013) was taken 7 days after discovery.
No sign of nova is seen in image (mag limit c. +16.6)
(recorded Nova location indicated by white circle)
