We confirm the nova candidate PNV J00422171+4112338 in M 31. The object is already visible on 9 x 60s stacked unfiltered CCD images obtained with the 0.43-m f/6.8 OU/OAM PIRATE CDK17 telescope (+ SBIG STL-1001E CCD camera with 1kx1k pixels each 24µm x24µm) at Costitx, Mallorca, Spain on 2011 September 12.879 UT, with a corresponding R magnitude of 17.8. The position for the nova candidate is RA = 00h42m21.68s, Dec = +41d12'33.3" (J2000, accuracy of 0.3"), which is 255" west and 215" south of the core of M 31. W. Pietsch for the M31 nova collaboration

Object detected at position end figures 21.72, 33.6 (UCAC2, J2000, accuracy of 0.1"). Magnitude 17.2C. Ka-Dar Observatory, TAU Station, Nizhny Arkhyz, Russia (MPC COD C32), telescope (D=400mm, F=3200mm) + STL-11000M + Clear, exp=3x120sec (summ), bin=2x2; V. Gerke, S. Korotkiy.

We performed optical low-dispersion spectroscopic observations of PN in M31 ( PNV J00422171+4112338 ) on 2011 September 14.643UT using the 1.3m Araki telescope(+LOSA/F2). The total exposure time is 3600 sec. The spectrum exhibits quite broad H-alpha and H-beta emission features. No other significant features could not be identified in our spectrum. The FWHM of the H-alpha emission line is about 4600 km/s. This suggests that the object would be a very fast nova and a candidate of recurrent novae in M31. M. Nagashima and A. Arai, Kyoto Sangyo University, Japan (http://www.cc.kyoto-su.ac.jp/~kao/blog/index.php/view/129).
