Cowie (UH/IfA)\n\n\nWe have imaged the field GRB060202 (Fox et al., GCN 4629)\nwith the UKIRT Wide Field Camera in J and K-band filters from\napproximately UT 05:00 to 08:20 on Feb 03.  \n\nObservations consisted of 10s expsosures in both J and K with a 9-point\ndither pattern with +/-6.4\" and 12.8\" offsets.  \nTotal integration times for J and K are 60 and 72 minutes, respectively.  \nImages were processed using the UKIRT real-time pipeline ORACDR and we \ntried to obtain a better background subtraction on the final coadded image.\nThe final image quality is limited by the poor seeing at low elevation and \ntelescope pointing, and has a PSF of 2\". \n\nWe detected a faint source inside the revised 4\" XRT error circle \n(Morris et al., GCN 4632) in K-band images.  \nThe location of this source is: \n\n   RA = 02:23:22.94,  DEC = +38:23:03.69 (J2000.0)  \n\n\nThis is consistent with the Keck/LRIS I-band detection reported \nby Cenko et al. (GCN 4636) within 1\".\nThe magnitude of this source is K = 19.86 with 3\" aperture diameter,\nusing nearby 2MASS stars for calibration.\nA PSF fit, however, suggests the point component may be almost a magnituder \nfainter and there may be some underlying diffuse emission.\n\nIn the J band image, we found no source within the XRT error circle\nto a 1 sigma limiting magnitude of J > 22.74 [2MASS].",
