Barrena-Delgado (IAC)\nreport on behalf of a larger collaboration:\n\n\"We have observed the error box of the INTEGRAL GRB 091202\n(Mereghetti et al. GCN 10234) in optical using the 0.8m IAC80\ntelescope and in NIR using the 1.5m TCS telescope, both located\nin Teide Observatory (Spain).\n\nOptical observations began at 1:26 UT of the 3rd Dec 2009 and\nincluded V, R and I imaging. We do not detect any new source\nwithin the XRT error box (Vetere et al. GCN10239). In particular\nin a 600s I band image with mean epoch 3.07 h after the burst\nonset we do not detect any new source down to a 3-sigma limiting\nmagnitude of I > 19.9 as compared to USNO-B1.0 star 1525-0212637\nfor which we assume a magnitude of I = 18.26.\n\nNIR observations starting at 04:03 UT were obtained with J, H\nand K filters, with a total of 1000s integration each. We do not\ndetect any new source within the XRT error box. In particular,\nwe obtain a 3-sigma limiting magnitude of K > 17.0 5.12 h after\nthe burst as compared with the 2MASS catalogue.\n\nThis message may be cited.\"",
