Optical spectra (range 3300-9500 Angstroms) of ASASSN-16kb (see ASAS-SN transient page and ASASSN-16kd/PNVJ17225112-3158349 (ATel #9469) were obtained on UT Sep 8 with the B&C spectrograph mounted on the du Pont 2.5m telescope at Las Campanas Observatory. A plot with the spectra can be found here. The spectra of both objects show a red continuum with H-alpha, Ca II triplet, and Fe II lines in emission, consistent with being highly reddened Galactic novae (see also ATel #9477 with initial spectroscopic classification of ASASSN-16kd by T. Bohlsen and ATel #9478). The H-alpha P-Cygni profile shows the emission peak and minimum absorption trough at +250/-190 km/s for ASASSN-16kb and +120/-800 km/s for ASASSN-16kd, respectively. Follow-up observations are encouraged.
