We report confirmation of Gaia Science Alerts supernovae candidates Gaia16bic, Gaia16bib and Gaia16biv. Images were obtained in G and R bands of the Maia instrument mounted to the Flemish 1.2m Mercator telescope at Roque de los Muchachos observatory, La Palma, Canary Islands, Spain, on 2016 September 20-22.

These new sources are close to galaxies, two of them seem to be increasing in luminosity, and they are not visible in archival 2MASS and DSS images. MAIA G band 400x400 pixel cut-out images are provided (N is up, E is left and scale is 0.276"/pix) at the following links: Gaia16bic, Gaia16bib and Gaia16biv.

The photometric calibrations were obtained using the Cambridge Photometric Calibration Server (CPCS), designed and maintained by Sergey Koposov and Lukasz Wyrzykowski. We acknowledge ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alerts).
