Tuomas Kangas report/s a classification of object: SN 2016ios

Type: SN II
Redshift: 0.017

Remarks: The transient matches a type II-P SN during the plateau phase (good matches between 40 -- 100 d). Constraining the age further is difficult due to the lack of a light curve or a recent non-detection. Clear features typical to type II-P, such as a P Cygni profile of H-alpha, the Ca II infrared triplet and Fe absorption lines are visible. The redshift is from the host galaxy.

The following Classification spectrum was provided:
