Antonelli (INAF/Rome),\non behalf of a larger collaboration, report:\n\n\nThe robotic 60-cm REM telescope located at La Silla (Chile) observed automatically\nthe field of GRB 111209A (Hoversten et al. GCN 12632) with the ROSS optical\nand REMIR near-infrared cameras in imaging mode.\n\nObservations started about 30 s after the Swift alert (about 5 min after the reported burst time)\nwhen the field was only 13 deg on the local horizon. \n\nSumming H band images from 7 to 13 min after the burst a weak counterpart is visible\nat coordinates RA=00:57:22.78 DEC=-46:48:04.2 (error approximately 0.5 arcsec on both axes)\nand with magnitude H = 14.7 +- 0.2, calibrated against the 2MASS catalogue.\nThe source is coincident with the optical counterpart reported by Klotz et al. (GCN 12633).\n\nFurther observations are in progress.\n\n[GCN OPS NOTE(09dec11):  Per author's request, LA was added to the author list.]",
