We report optical spectroscopic observation of supernova candidates ASASSN-17bp/2017wi (ATel #10023) and ATLAS17abh/2017ae using OSMOS (range 398-686 nm) mounted on the MDM 2.4m telescope at KPNO. Targets were discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) and ATLAS project. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to identify the type and phase of the SN spectra.

(1) The redshift is estimated from H_beta and OIII (4960.3 & 5008.2 \AA) host emission lines. It is also consistent with SNID estimated redshift.
(2) The redshift is estimated from SNID template cross-correlation.
