G. Cannizzaro, on behalf of NUTS report/s a classification of object: SN 2016hkn

Type: SN II
Redshift: 0.022

Remarks: Previously classified by Pan et al. as a Type IIb SN (ATel #9696). The spectrum is relatively flat in the continuum, and shows broad, P-Cygni profiles in Halpha, and Ca lines. The minimum of the absorption in Halpha is at a velocity of ~14,000 km/s, and the spectrum is consistent with a Type II SN a few weeks after explosion. The absolute magnitude (-17.5) is relatively bright for a Type IIP SN, but is consistent with other IIb SNe.

The following Classification spectrum was provided:
