GCN 11823) using the KASINICS instrument on\n  the 1.8m telescope at Mt. Bohyun Observatory in Korea.\n\n   We clearly detect the NIR counterpart in K (Morgan et al. 11845;\n  Levan et al. GCN 11846). Using 2MASS stars in the vicinity,\n  we obtain K ~ 16.86 +- 0.02 mag (statistical error only)\n  for the NIR counterpart.\n\n   The brightness of the object is consistent with the value reported\n  in Levan et al. (GCN 11846), implying no significant brightening over\n  about 18 hrs time span.\n\n   Further NIR observations are being carried out.",
