Kubanek (FZU AV CR \nPrague), report on behalf of a large collaboration:\n\nWe imaged the field of IGR J17062-6143 detected by Swift (trigger \n525148) with the Watcher robotic telescope (D=40cm) located at Boyden \nObservatory, Bloemfontein, South Africa.\n\nThe first on-target observation started 300 seconds after the BAT \ntrigger time of 22:42:31 UT and before the earliest PROMPT observations \nreported in GCN 13390. The initial airmass was 1.2 and conditions were \nnon-photometric.\n\nThe initial two exposures were taken in the Clear filter and were 30 \nseconds long.\n\nWe detect a source at the position of the UVOT source (GCN 13386) in the \nfirst image with R-band magnitude of 14.8 � 0.3 (4-sigma) with the \nlimiting magnitude in the frame being 15.6 mag (2-sigma upper limit). In \nthe second image the source is not detected, but the limiting magnitude \nis 15.1. These results are not sufficient to confirm fading behavior as \nseen at later times by PROMPT (GCN 13390) and GROND (ATEL 4214). Later \nimages obtained by Watcher are being analysed.\n\nMagnitudes were estimated using the nearby USNO-B1 stars as references \nand are not corrected for galactic dust extinction.",
