We report spectroscopic observations of the recent M31 nova candidate PNV J00421003+4105141, which was discovered by K. Nishiyama and F. Kabashima at m=17.7 (unfiltered) on 2011 Nov. 12.504 UT. At our request, a spectrum (410–950 nm) was obtained by J. Caldwell approximately 4 days post discovery on 2011 Nov. 16.26 UT with the 9.2m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph). The spectrum reveals relatively narrow Balmer, Fe II, and O I emission lines (FWHM Hα ~ 1000 km/s; EW Hα ~ -20.0 nm) superimposed on a flat continuum. These observations confirm that the object is in fact a nova in M31, and that it is a member of the Fe II spectroscopic class.
We thank K. Nishiyama and F. Kabashima for alerting us to the object, and K. Hornoch for supplying an improved finding chart. A.W.S. thanks the NSF for support through AST-1009566.
