Another photometry results were B=12.16, V=10.98, Rc=10.37 and Ic=9.83 with 0.43-m f/6.8 CDK astrograph + FLI PL4710 CCD at iTelescope.NET, SSO, NSW, Australia, I took low resolution spectra but I can detected no significant feature (at leat, it is not late type star like Mira variables).

The likely nova is located 4 arc minutes NE of gamma Scuti.

*** Spectroscopy and multiband photometry are urgently required. ***

Clear skies,
