We report the spectroscopic classification of Gaia17deh. The target was supplied by the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts). The observations were performed on 20171207 UT at the 4.1m SOAR Telescope equipped with the Goodman High Throughput Spectrograph using the 600 lines/mm grating, 2 × 2 binning and a slit width of 1.5 arc second, resulting in a spectral coverage from 445-714 nm with a resolution 0.6 nm.
