Fan (Steward Observatory, University of Arizona)\nreports:\n\nUsing the Simultaneous Quad Infrared Imaging Device (SQIID) on the Kitt\nPeak Mayall 4-meter Telescope, we observed GRB 071025 in J, H, K bands\nsimultaneously, beginnig at UT 2007-10-25-05:56:59. With total exposure\ntime of 240 sec in all three bands, we clearly detected the afterglow.\nCalibrated using local 2MASS sources, the object is at\n\n J=17.34 +/- 0.05\n H=16.37 +/- 0.05\n K=15.45 +/- 0.05\n\nThe photometric errors are dominated by the zeropoint uncertainties from our\n calibration procedure. The photon noise on the measuremens is <0.01.\n\nThe message may be cited.\n\n\n\n-- \n\nXiaohui Fan\nSteward Observatory\nThe University of Arizona\n933 N.
