Milano Bicocca, INAF-OAB)\non behalf of the REM/ROSS team report\n\nThe robotic telescope REM observed the field of GRB040903 (IBAS #alert 1972,\nGotz et al., GCN 2690) with the IR camera REMIR in the filter H starting on\nSept. 03 at UT 22:58, 4.67 hrs after the first INTEGRAL alert.\nDue to the poor weather conditions only one set of five 1s dithered images,\nfor a total exposure time of 5s, was acquired. The acquisition and image\npreprocessing were done automatically. The photometry was calibrated with\na subset of the 2MASS catalog.\nOff-line analysis revealed no evident new sources, compared to the 2MASS\ncatalog, within the error circle of INTEGRAL. \nThe detection upper limit (3 sigma) is H=15.2 and the extinction in the area \nis A_H=2.56.\n\nThis message can be cited.",
