NOVA IN M31 = M31N 2013-10a = PNV J00432422+4118192
     Further to CBET 3664, A. Bigley, K. Fuller, K. Hayakawa, W. Zheng, W.
Li, and A. V. Filippenko, University of California at Berkeley; and S. B.
Cenko, Goddard Space Flight Center, report the LOSS discovery of a nova (mag
19.1) in M31 on unfiltered KAIT images taken on Oct. 3.31 UT; the new object
is locate at R.A. = 0h43m24s.22, Decl. = +41d18'19".2 (equinox 2000.0), which
is 450" east and 130" north of the center of the galaxy.  Additional
approximate KAIT magnitudes for the nova:  Sept. 30.3, [19.7; Oct. 5.3, 18.5;
6.3, 18.6.  A finding chart was posted at the following website URL
http://astro.berkeley.edu/~zwk/findingchart/PNV_J00432422+41181915.jpg.
The variable was designated PNV J00432422+4118192 when it was posted at the
Central Bureau's TOCP webpage and is here designated M31N 2013-10a based on
the spectroscopic confirmation reported below.

     W. Zheng, P. L. Kelly, M. L. Graham, K. I. Clubb, O. Fox, B. E. Tucker,
I. Shivvers, and A. V. Filippenko, University of California, Berkeley; and
S. B. Cenko, Goddard Space Flight Center, NASA, report that PNV
J00432422+4118192 is an "Fe II" spectroscopic-class nova.  A CCD spectrogram
(range 450-960 nm), obtained with the 10-m Keck II telescope (+ DEIMOS
spectrograph) on Oct. 8 UT, exhibits a blue continuum with strong H-alpha and
H-beta emission lines superposed, along with several Fe II emission lines.
