We report spectroscopic confirmation and classifications for reported Gaia Photometric Science Alerts (http://gaia.ac.uk/selected-gaia-science-alerts). All spectra were taken at the 2.5m Isaac Newton Telescope on La Palma, over the nights of 24-25 May. Low resolution spectra were taken using IDS/RED+2/R300V.
