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.

 Survey Name | IAU Name  | Obsv. Date    | Spec. Type | Phase (w.r.t max) |  Redshift | Notes  
---------------------------------------------------------------------------------------------- 
 ASASSN-17bp | SN 2017wi | 2017-01-31.10 | Ia-norm    |  +7 to +10d       |  0.051    |  (1)   
 ATLAS17abh  | SN 2017ae | 2017-01-29.09 | Ia-norm    | +10 to +13d       |  0.022    |  (2)

(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.
