We report spectroscopic confirmation and classifications for reported Gaia Photometric Science Alerts (http://gaia.ac.uk/selected-gaia-science-alerts), together with targets from the All-Sky Automated Survey for Supernovae (ASAS-SN; Shappee et al. 2014) and the TOCP list. All spectra were taken with the 4.2m William Herschel Telescope on La Palma, over the nights of 11 to 12 June. Low resolution spectra were taken using ISIS with the R158R and R300B gratings. The classifications were done with SNID (Blondin and Tonry 2007, ApJ, 666, 1024).
