We report the spectroscopic classification of two nuclear transients: Gaia17bvp and ASASSN-17jl/AT2017foy.
A low resolution (R = 350) SALT/RSS spectra was taken on 2017-07-27, under the SALT Large Programme on transients (2016-2-LSP-001).
Both transients shows spectrum similar to SN Type Ia few days before maximum.
The spectroscopic classification was done using SNID code (Blondin & Tonry 2007, ApJ, 666, 1024). Additionally, in both spectra is present broad Halpha emission lines most likely originated form nucleuses of host galaxies.
