Following the observations reported by Tomasella et al. (GCN 18561) and Benetti et al. (GCN 18563), we re-observed the optical transient iPTF15dld reported by Singer et al. (GCN 18497), located in the skymap of the advanced LIGO and Virgo trigger G194575 (Singer et al., GCN 18442). Optical spectroscopic observations were carried out at a mid time of 2015 Nov 6.949 UT with the 3.6m Italian TNG telescope (Canary Islands, Spain), equipped with the DOLORES camera using the grism LR-B (wavelength range 3000-8000 AA). Optical imaging observations were carried out with the Italian Asiago 1.82 m Copernico Telescope equipped with the AFOSC camera in the uBVriz filters at a mid time of 2015 Nov 6.870.
