P. D'Avanzo, M. Cecconi, C. P. Padilla-Torres (INAF/TNG) report on behalf
of the CIBO collaboration:

We observed the field of GRB 130418A (De Pasquale et al., GCN 14377) with
the TNG telescope located in the Canary Islands. We obtained a set of
J-band images with the NICS camera on May 1.891 (mean observing time;
about 13.1 days from the GRB).

No source is detected at the optical afterglow position (De Pasquale et
al. GCN 14377; Gorosabel et al. GCN 14378; Quadri et al. 14379; Kuin et
al., GCN 14384; Hentunen et al., GCN 14394) down to a 3sigma limiting
magnitude of J~21.3 (calibrated against the 2MASS catalogue).
