Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN II0.0175Global SN ProjectUsing 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.


Object coordinates updated according to AT-report 28045 of Group Pan-STARRS1
Previous RA, DEC: 08:20:17.352, +20:52:32.16 (125.0723, +20.8756)
Updated RA, DEC: 08:20:17.348, +20:52:32.15 (125.072283799, 20.8755978866)

This is apparently MASTER OT J082017.38+205232.2 (Pogrosheva et al. 2018, ATel, 12038)
and is not an SN Hunt discovery.

The discoverer was actually Nikolay Mishevskiy.
