Jose Prieto, Stu Parker, Ben Shappee report/s a classification of object: SN 2016blx

Type: SN II
Redshift: 0.010422

Remarks: The spectrum shows a blue continuum with broad Balmer P-Cygni profiles, consistent with a normal Type II SN a few days after explosion. After correcting for the redshift of the host galaxy, we measure an H-alpha velocity of -9400 km/s from the minimum of the P-Cygni absorption trough. We also detect a broad absorption feature to the blue of H-alpha at 6215 Angstroms, which is seen in some spectra of young Type II SN and has been identified as the Si II 6355 feature. The velocity of this profile would be -6700 km/s if its Si II.

The following Classification spectrum was provided:

Obsdate: 2016-04-10 01:02:53
Instrument: MagE
Telescope: Walter Baade Magellan 6.5-m telescope (LCO)

Remarks: A medium resolution optical spectrum (R ~ 4000; wavelength 320-1000nm) was obtained with the Magellan Echellette Spectrograph (MagE) mounted on the Magellan 6.5-m Baade telescope on UT 2016 April 10.04.
