Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki (Teppo-cho, Yamagata, Japan) of a possible nova (mag 18.2) in M31 on unfiltered CCD survey frames taken on Nov. 26.498, 28.643, and 29.385 UT using a 0.60-m f/5.7 reflector. The new object, initially designated M31N 2008-11c by the Central Bureau, is located at R.A. = 0h43m18s.62 +/- 0s.04, Decl. = +42o10'14".2 +/- 0".1 (equinox 2000.0). Nothing was visible at this position on an image taken by Itagaki on Nov. 5.511 (limiting mag 20.0) or on the Digitized Sky Survey (no details provided). R. M. Quimby and M. M. Kasliwal, California Institute of Technology, report that spectroscopy (range 360-900 nm) of M31N 2008-11c obtained on Dec. 4.22 UT with the Double Beam Spectrograph on the Palomar Hale 5-m telescope reveals broad absorption features including the Si II 635.5-nm doublet, S II 545.4- and 564.0-nm, and Ca II H and K (among other features) -- consistent with a normal type-Ia supernova near maximum light at an approximate redshift of z = 0.07 (i.e., well beyond M31). The supernova designation 2008hz is thus being assigned to this object. H. Yamaoka, Kyushu University, adds that a diffuse object northeast of 2008hz is probably the host galaxy: it was catalogued as a globular- cluster candidate by Sargent et al. (1977, A.J. 82, 947; "SKHB 220") and in the Bologna catalogue (Battistini et al. 1987, A.Ap. Suppl. 67, 447; Galleti et al. 2004, A.Ap. 416, 917; "Bol 469"), but spectroscopy has revealed that it is a background galaxy at v_r = 21900 km/s (Galleti et al. 2006, A.Ap. 456, 985); Yamaoka notes that this recession velocity is coincident with that of Quimby and Kasliwal, above.
