A bright M33 transient, PNV J01325723+3024260 (tentatively identified as M33N 2012-10a), was discovered on 2012 Oct. 04.583 UT by K. Nishiyama and F. Kabashima at m = 15.8 (unfiltered). After apparently fading to m = 17.2 on Oct. 06.661 UT, the object re-brightened to m = 16.1 on Oct. 07.644 UT.
At our request, a spectrum (410–900 nm) of PNV J01325723+3024260 was obtained by S. Odewahn with the 9.2m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph) on 2012 Oct. 08.19 UT, approximately 4 days post discovery. The spectrum (available through the link below) is dominated by relatively narrow Balmer and Fe II emission features (FWHM Hα ~ 1100 km/s), superimposed on a flat continuum. These observations confirm that PNV J01325723+3024260 is a nova in M33, and that it is a member of the Fe II spectroscopic class.
We thank Koichi Nishiyama and Fujio Kabashima (Miyaki-Argenteus Obs.) for bringing this object to our attention immediately after discovery. A.W.S. is grateful to the NSF for support through AST-1009566.
