Carnegie Supernov Project reports the optical spectroscopic classifications of five transients. The spectra were obtained on Sep 27 UT with the Las Campanas 2.5-m du Pont telescope (+ WFCCD). The LSQ transient was supplied by the La Silla-Quest survey (Hadjiyska et al., ATel #3812).

Notes
1) The discovery was reported in ATel #6500.
2) The discovery was reported in ATel #6493.
3) The redshift is derived from the SN spectrum.
4) The spectrum is similar to those of young 91T-like objects.
5) The spectrum is similar those of SN2008S (Smith et al. 2011).
