We obtained four 240-s narrow-band H-alpha and four 120-s R-band CCD frames of M33 on 2014 July 29.206 and 29.222 UT, respectively, with the 2.5-m Isaac Newton Telescope (INT) + WFC at La Palma under ~1.1" seeing. The single frames were co-added and the co-added images were used for photometry of the spectroscopically unconfirmed M33 nova candidate PNV J01340288+3035111 (ATel #6331, #6350) yielding H-alpha = 18.06 ± 0.06 and R = 20.18 ± 0.09 mag.
The strong H-alpha emission observed in the INT data strongly supports classification of the PNV J01340288+3035111 as nova in M33.
This work is based on observations made with the Isaac Newton Telescope operated on the island of La Palma by the ING in the Spanish Observatorio del Roque de los Muchachos. We thank H. Kucakova for getting M81 images at Ondrejov.
