We confirm the optical transient PNV J17184504-2454221 as a Galactic nova, based on spectroscopy from the SOAR 4.1m telescope. This nova is located at RA=17 18 45.04, Dec= -24 54 22.1 (J2000) in the constellation Ophiuchus and was discovered on 2017 Nov 11.37 by S. Kaneko. The spectrum was obtained with Goodman Spectrograph on 2017 Nov 13.00 UT, covering 3300--7100 A with a resolution of 6.2 A. The spectrum shows broad Balmer emission lines with FWHM of 2500 km/s. Beyond the Balmer lines, the most prominent emission lines are Fe II, implying that it is an Fe II nova. Additional optical observations of this nova are desirable, but likely to be extremely challenging as it is near the Sun.
