Andrew Howell, Curtis McCully, David Sand, Leonardo Tartaglia LCOGT SN-KP SN II 0.009 1 LCOGT SN-KP The spectrum is low signal-to-noise but shows a blue continuum with H-alpha and H-beta emission, possibly including a broad component, at the redshift of the host galaxy (z=0.009; HIPASS Catalog via NED). We therefore tentatively classify it as a Type II supernova. 2017TNSCR.169....1H
