The limiting magnitude in  the central part of the K'-band image\n(mosaic) is about  K'=19.5 after adding all frames  taken at different\nposition angles  of the wire-grid polarizer. Since  standard stars are\nnot yet available we estimate the error of this magnitude limit to +/-\n0.5  mag. The combined  image covers  about 90%  of the  revised error\ncircle (in 't Zand et al., GCN #1123).\n\nAt the position of the radio  transient reported by Taylor et al. (GCN\n#1136) no source is detected (see also Hammell et al., #GCN 1126).\n\nWe do  not detect the  I-band source reported  by Halpern et  al. (GCN\n#1139).\n\n\nThis message is quotable.",
