Rudy, Lynch, Prater, Mazuk, Gilbert, Puetter, and Perry report
that spectroscopy, obtained as above, of the apparent nova 2007-12b
in M31 (cf.
http://www.cfa.harvard.edu/iau/CBAT_M31.html) on 2007
Dec. 15 UT shows a remarkably bright H_alpha line of very high
equivalent width. Owing to the low signal-to-noise ratio on this
faint object, no continuum was detectable, and the only other
emission lines seen were Paschen beta, gamma, delta, and He I
1.0830-microns. The FWHM of these lines were about 5000 km/s --
notably broad for a nova. The FWZI of H_alpha was about 6800 km/s.
