A series of images were obtained with the J filter on 2019-12-18 from 19:16:04 to 19:59:02 UT (i.e. about 5.6 days after the GW event). The transient is clearly detected with a magnitude J(AB) = 19.6 +/- 0.1 (obtained from preliminary psf photometry calibrated against the 2MASS catalogue and subtracting the host galaxy contribution).
