Kabashima and present a pre-discovery detection that allows us to tightly constrain the time of outburst for this object. The nova candidate was discovered by Nishiyama and Kabashima (Miyaki-Argenteus observatory, Japan) on 2009 September 3.752 UT, with no object visible at its position on September 1.566 UT (private communication).},
