We report confirmation of Gaia Science Alert transients Gaia15adt and Gaia15aek. Images were obtained through U, G, and R filters of the MAIA instrument installed on the 1.2m Mercator telescope at Roque de los Muchachos on April 06-11, 2015.
Gaia15adt is visible approximately 10" NE from the SDSS J140114.76+441829.4 spiral galaxy core.
Gaia15aek is superimposed on SDSS J064701.23+645600.1 galaxy, approximately 2.5" NE from the core.
New sources are not present in archival 2MASS, DSS and SDSS images. Their proximity to neighbouring galaxies makes them supernova candidates.
