An observation with the Chiron Echelle Spectrograph on the SMARTS/CTIO 1.5m on 2015 February 13 at 09:38UT confirms that this object, reported by P. Schmeer in vsnet-alert 18276 on 11 February, is a nova. H-alpha has an equivalent width of -14 nm and an FHWH ~ 2000 km/s. There are symmetrically-displaced emission features at about +/- 4500 km/s which resemble those seen in fast He-N novae. H-alpha and H-beta show P Cyg absorption features at about -4200,-3200, and -2300 km/s. O I 777 nm and 845 nm are in emission. A strong emission line at 588 nm with a prominent P Cyg absorption is either He I 587 nm or modestly blueshifted Na I. Broad (2000 km/s FWZI) He I 706 nm emission may be present. Similarly broad emission is seen in the prominent Fe II multiplet 42 lines at 492, 502, and 517 nm, though the first two may have some He I contribution. The apparently rapid fading and bright possible near-IR counterpart (P. Schmeer, followup to vsnet-alert 18276) suggest this is a system with an M giant donor, like V745 Sco or N Sco 2014.
