We report confirmation of Gaia Science Alerts transients Gaia17aub and Gaia17awk. 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 2017 March 30th - 3rd April.

These new sources are not visible in archival 2MASS and DSS images. ECAM modified Gunn R band 300x300 pixel cut out images are provided (N is up, E is left, the scale is 0.215"/pix, dead pixels are masked) at the following links: Gaia17aub and Gaia17awk.

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).
