J. L. Prieto, G. Simonian report/s a classification of object: SN 2016idl

Type: SN IIn
Redshift: 0.058

Remarks: We obtained a spectrum (range 3960-6850 Angstroms) of AT2016idl on UT 2017 Jan 7.34 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum of AT2016idl shows Hbeta, Hgamma and Hdelta emission lines, as well as He I 5875, characteristic of a Type IIn SN. The Hbeta emission line profile can be well fit with 2 Gaussian compoments with FWHM = 1700 km/s and 5400 km/s. The redshift measured from the peak wavelengths of the Hbetta and Hgamma emission lines is z=0.058.

The following Classification spectrum was provided:
