We report confirmation of Gaia Science Alerts transients
Gaia16bhu,
Gaia16bhk,
Gaia16bho and
Gaia16bhr.
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 18-19.
These new sources (close a galaxy in the case of Gaia16bho) are not visible in archival 2MASS and DSS images:
Gaia16bhu,
Gaia16bhk,
Gaia16bho and
Gaia16bhr.
MAIA G band 400x400 pixel cut-out image is provided (N is up, E is left and scale is 0.276"/pix).
