PNV J16484962-4457032 was discovered by H. Nishimura on UT 2018 Feb 6.86. Subsequent spectroscopy of this transient by S. Kiyota on 2018 Feb 7.73 was consistent with an identification as a classical nova. We obtained a spectrum of this source with the Goodman Spectrograph on the SOAR telescope on 2018 Feb 12.39, covering a wavelength range of about 3800-7800 A at a resolution of 5.8 A. The spectrum shows broad Balmer emission, with an Halpha FWHM of about 3000 km/s and Hbeta FWHM of about 1850 km/s. There are many Fe II lines and strong O I at 7773, which indicate a classification as a nova of the Fe II class. The nova is highly reddened, consistent with its low Galactic latitude of b=-0.06.
