We report optical spectroscopic observations of 4 ASAS-SN supernova candidates (ATel #8012, #8041, #8051) obtained on UT 2015 Sep. 12 and Sep. 18 with OSMOS (range 398-686 nm) mounted on the MDM 2.4m telescope at KPNO. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type and phase of the SN spectra. We also measured the minimum of the Si II 6355 absorption trough in the Type Ia SNe around maximum light.
