We observed the field of the optical/NIR candidate reported by Itoh et al. (GCN Circ. 18742) with the 3.6m Italian TNG telescope (Canary Islands, Spain), equipped with the DOLORES camera in imaging mode starting on 2015 Dec 29.9292 UT. 

No object is detected at the reported position of this optical/NIR candidate down to a 3sigma limiting magnitude i~23 (AB; calibrated against SDSS stars in the field). A bright (i~17.6 AB mag) object, not present in the SDSS, is detected at RA, Dec (J2000): 01:56:23.75, +04:33:48.1.
As suggested by Cenko et al. (GCN Circ. 18762) our findings are consistent with this object and the optical/NIR candidate reported by Itoh et al. (GCN Circ. 18742) being the minor planet 2606 Odessa.
