Jamison Burke, Iair Arcavi, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Stefano Valenti report/s a classification of object: SN 2018hyw

Type: SN II
Redshift: 0.0175

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find multiple good fits to SNe II. The supernova is likely around two months after max, although the H alpha emission is exceptionally broad and strong. We measure the velocity of the H absorption to be 9000 km/s. The measured redshift of 0.0175 is derived from fitting the narrow H alpha emission from the host.
