We observed the field of GRB 110106A (Mangano et al., GCN 11520) in the 
K band with the 3.6m TNG equipped with NICS. A total of 60 min 
integrations were obtained with a mean time Jan 7.07 UT (10.33 hr after 
the GRB).

We detect no sources within the refined X-ray position (Osborne et al., 
GCN 11526; see also, down to a 
3-sigma limiting magnitude K > 20.3. We clearly detect the z=0.093 
galaxy just outside the error circle (Malesani et al., GCN 11524; 
Piranomonte et al., GCN 11530), with a magnitude K=14.90 +- 0.06 
(calibration against 2MASS stars in the field).
