The AZTEC (Arizona Transient Exploration and Characterization) collaboration reports an optical spectrum of PS15cwx (ATEL #8299) obtained on UT 2015 Nov. 19.33 with the 2.3m Bok telescope (+ Boller & Chivens spectrograph) on Kitt Peak, Arizona. Cross-correlation using SNID (Blondin & Tonry 2007) finds good matches with SNe Ia-91T (e.g., SN 1999ac) before optical maximum and with a redshift near 0.046.
