Referred to by ATel #: 7021

We report optical spectroscopic observations of three ASAS-SN SNe (ATel #6950, #6979, #6983) obtained on UT 2015 January 25 with WFCCD (range 3600-9200 Angstroms, FWHM res. 7 Angstroms) mounted on the 2.5-m du Pont telescope at LCO. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type, phase and redshift of the SN spectra. We also measured the minimum of the Si II 6355 absorption trough.
