On UT June 20, 2017, we obtained spectra of nine optical transients with the Wide Field Spectrograph (WiFeS - Dopita et al., 2007, ApSS, 310, 255) on board 2.3m ANU telescope at Siding Spring Observatory. We classify four of them as Type Ia Supernova (SN Ia) by cross-correlating with a library of supernova spectra using the "Supernova Identification" code (Blondin & Tonry, 2007, ApJ, 666, 1024). The other five transients, fainter than 19 mag, did not show any supernova spectral feature. Of them, one transient turns out to be an AGN, one M-dwarf, and the rest are galaxies. We present results in the following table:
