Nagayama (Nagoya Univ.) on behalf of the IRSF Collabration\nreport:\n\nWe searched for a NIR afterglow of GRB091026 (Markwardt et al., GCN\n10081) starting from 18:43:32.3 UT on 2009 Oct 26 (5.5 hours after the\nburst) with the SIRIUS on the IRSF 1.4m telescope at SAAO in South Africa.\nIn images of a 300sec exposure with J, H and Ks filter, we did not find\nany object within the error circle of the Swift XRT source position\n(Evans. et al., GCN 10084).\n\nA 5 sigma upper limits are the followings.\n\nJ > 18.35\nH > 17.39\nK > 16.70\n\nThis photometry was done by using the DoPhot and calibrated against the\n2MASS cataloged stars",
