Andrew Howell, Curtis McCully, Stefano Valenti LCOGT SN-KP SN Ib 0.008731 1 1 LCOGT SN-KP Using Superfit (Howell et al. 2005, ApJ, 634, 119), we find a good fit to the Type Ib SN 1999dn 10 days after maximum light at the redshift of the proposed host galaxy (z=0.009; HIPASS Catalog 2006, via NED). We find He I absorption features at an expansion velocity of ~9000 km/s. 2016TNSCR.364....1H
