Optical and IR spectra from 0.47-2.5 microns (resolution: 6-30 angstroms) of V2860 Orionis (Nova Orionis 2019) were obtained 2019 August 24.50 (UT) with the Aerospace Corporation's 1.0 m telescope using its Visible and Near-Infrared Imaging Spectrograph (VNIRIS). These observations confirm the classification of V2680 Ori as a He/N nova (#ATel 13027). The O I lines at 0.8446 and 1.1287, which are fluorescently excited by Lyman Beta, are very strong and suggest a low reddening of E(B-V) < 0.3 despite the gradual decline of the continuum to shorter wavelengths. The He II lines were just beginning to emerge at the time of these measurements.
