Xu (WIS) and\nI. Skillen (ING) report:\n\nWe imaged the field of GRB111215A (Oates et al. GCN12681) using the\nWHT, the LT and the NOT, all on La Palma, on the night of 2011-Dec-15 (UT).\nSeeing conditions were rather poor (FWHM~2\"), and no counterpart was\nlocated to the following 3-sigma limits at the given mid-times post-burst:\n\nWHT/LIRIS (calibrated against 2MASS)\nK>19.3 at 4hr 55m\nJ>19.4 at 5hr 15m\n\nLT/RATCam (calibrated against SDSS)\nz'>21.7 at 6hr 50m\n\nNOT/StanCam (calibrated against SDSS)\nz'>22.5 at 6hr 50m\n\nThe K-band limit is consistent with that provided by D'Avanzo et\nal. (GCN12695) from the TNG, and confirms this source to be dark even\nin the infrared.\n\nWe are grateful to Ilia Ilyin for assistance in obtaining the NOT observations.",
