The broad H-alpha p-cygni absorption at ~8000 km/s is very atypical for Type II SNe so late (>150 days) after discovery, but similar to what was seen in the peculiar Type II SN iPTF14hls. 2018TNSCR2158....1A

Andrew Howell, Curtis McCully, Stefano Valenti Global SN Project SN II 0.01 1 Global SN Project The spectrum shows a blue continuum with a broad H-alpha P Cygni profile. We therefore classify it as a young Type II supernova. 2018TNSCR.373....1H
