L. Angelo Antonelli (INAF/Roma), A. Harutyunyan (INAF/TNG), G. Tessicini
(INAF/TNG), G. Andreuzzi (INAF/TNG), report on behalf of a larger
collaboration:
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 http://www.swift.ac.uk/xrt_positions), 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).
