We obtained a spectrum of the Gaia Science Alerts transient Gaia16bak (http://gsaweb.ast.cam.ac.uk/alerts/alert/Gaia16bak/) on 2016 September 4.02 UT at the 1.5m G.D. Cassini Telescope (Loiano) with BFOSC. The spectrum, obtained with gr4 and a 2" slit, cover the ~3800-8500 A range with a resolution of ~13 A. The best match obtained with the GEneric cLAssification TOol (GELATO, Harutyunyan et al. 2008, A.Ap. 488, 383; available at URL https://gelato.tng.iac.es/login.cgi) is with the type IIL SN 1996al, ~23 days from explosion, assuming z=0.025.
