Tessicini (INAF/TNG) on behalf of the CIBO collaboration, report:\n\nWe observed the field of GRB 110106A (Mangano et al., GCN 11520) using \nthe 3.6m TNG telescope, located in the Canary Islands. A set of R- and \nI-band images were acquired starting on Jan 6.8265 UT (4.41 hr after the \nGRB) for a total exposure time of 20 minutes per filter. The seeing was \n1.5\" in the R band.\n\nWithin the XRT error circle (Mangano et al., GCN 11520), we marginally \ndetect a source in both R and I. Its coordinates are (J2000):\n\nRA = 05:17:14.14\nDec = 64:10:28.1\n\nand its magnitude is R ~ 24.5. In addition, we note the presence of a \ngalaxy just outside the current X-ray error circle (its centroid being \n7.3+-3.6\" away of the XRT position). It is visible also in the DSS \nimages and has a magnitude R = 18.2 (assuming R = 17.54 for the star at \nRA=05:17:11.43, Dec=+64:10:10.88).\n\nWe cannot assess whether any of the sources are variable, and so their \nrelation to GRB 110106A remains to be proven.\n\nFurther observations are in progress.\n\n[GCN OPS NOTE(06jan11): Per author's request, GT was added to the author list.]",
