Leicester) report on behalf of a larger collaboration:\n\nWe have imaged the field of GRB100614A (Stratta et al., GCN 10837) with\nthe Gemini Near InfraRed Imager on the 8-m Gemini North telescope.\nObservations were obtained in the Y, J, and K filters beginning at 7:05 UT\non 15 June 2010 (~ 9.5 hours after the burst).\n\nWe find no sources inside the revised XRT error circle (Osborne et al.,\nGCN 10849) to limiting magnitudes of J > 22.7, K > 21.6 (Vega mags,\ncalibrated with respect to 2MASS).  The lack of optical/NIR detections at\nother facilities (Mundell and Steele, GCN 10838; Jelinek et al., GCN\n10839; Levan et al., GCN 10840; Gorbovskoy et al., GCN 10853, Malesani et\nal., GCN 10854, Holland and Stratta, GCN 10857), coupled with the moderate\nexcess column inferred from the XRT spectrum (Margutti et al., GCN 10846),\nsuggest a highly extinguished optical/NIR afterglow.",
