We report confirmation of Gaia Science Alerts transients
Gaia16asc,
Gaia16ase,
Gaia16asj and
Gaia16ask.
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 July 02 - 04.
These new sources are supernovae candidates near galaxies and they are not visible in archival 2MASS and DSS images:
Gaia16asc,
Gaia16ase,
Gaia16asj and
Gaia16ask.
MAIA G band 400x400 pixel cut-out image is provided (N is up, E is left and scale is 0.276"/pix, dead and saturated pixels are masked and represented with a white colour).
