Yoshii (University of Tokyo),\nreport on behalf of the TAO project team:\n\nWe observed GRB 101023A (Saxton et al., GCN 11363) with\nthe near-infrared camera ANIR mounted on the miniTAO 1.0m\ntelescope at the University of Tokyo Atacama Observatory\non the summit of Co. Chajnantor (5640m altitude) in\nthe northern Chile.\n\nThe J-, H-, and Ks-band observations started from\n2010-10-24 02:48 UT (3hours after the burst), and total\nexposure time was 540sec for each band. The afterglow was\ndetected in all the three bands at the position reported\nby Levan et al. (GCN 11366). The seeing was 0.9-1.0arcsec\nthroughout the observations, and the image of the afterglow\nwas clearly separated from the nearby bright star.\n\nAB magnitudes are are listed below, where the flux calibrations\nwere carried out using 2MASS stars within the FoV.\n\nBand   Mid-UT    AB-Mag\n----------------------------\nKs      02:53:05  19.40 +/- 0.10\nH       03:07:41  20.28 +/- 0.27\nJ       03:24:36  19.92 +/- 0.14\n----------------------------",
