We report confirmation of Gaia Science Alerts transients Gaia16ali and Gaia16alj. Images were obtained through modified Gunn R band filter of the ECAM instrument installed on the Swiss 1.2m Euler telescope at La Silla, on 2016 April 19 - 22 UT.
These new sources are supernovae candidates and they are not visible in archival 2MASS and DSS images: Gaia16ali (near centre of galaxy GALEXASC J041551.89-621715.5) and Gaia16alj. ECAM modified Gunn R band 800x600 pixel cut out image is provided at the previous links (N is up, E is left, the scale is 0.215"/pix, dead pixels are masked and represented with a white colour).

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 (
