We report the spectroscopic classification of a nuclear transient Gaia17bhd (AT2017edu), also known as MASTER OT J122100.9-533150.1, discovered by MASTER-OAFA auto-detection system ( Balanutsa et al, ATel #10291) and Gaia Science Alerts system (http://gsaweb.ast.cam.ac.uk/alerts/alert/Gaia17bhd). The spectrum was obtained using the Robert Stobie Spectrograph (RSS) on the South African Large Telescope (SALT). Spectroscopic classification was done using SNID code (Blondin & Tonry 2007).
