We report the spectroscopic classification of several transients based on observations taken with the Nordic Optical Telescope (NOT) equipped with ALFOSC, over the nights 23-25 August 2017. Targets were supplied by the ATLAS survey (see Tonry et al., 2011, PASP, 123, 58) and from the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts). Classification spectra and additional details can be obtained from the IAU Transient Name Server.
