Y.-C. Pan, C. Rojas-Bravo, R. J. Foley (UCSC), S. W. Jha (Rutgers), A. Rest (STScI), D. Scolnic (Chicago/KICP) report/s a classification of object: SN 2017ijn

Type: SN IIn
Redshift: 0.05

Remarks: SN IIn. ATel 11009: Blue continuum with strong, relatively narrow Balmer emission lines. For H beta, we measure two components withs FWHMs of 400 and 2300 km/s, respectively. At z = 0.048 (as measured from the center of the emission lines), the object has M ~ -18.7 mag, making it a likely SN rather than an LBV outburst despite some spectral similarities to LBV outbursts such as SN 2009ip
