SN IIn

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
