TITLE: GCN CIRCULAR NUMBER: 13396 SUBJECT: Watcher follow-up observations of IGR J17062-6143 (Swift trigger 525148) DATE: 12/06/28 11:33:33 GMT FROM: Seamus Meehan at U College,Dublin S. Meehan, L. Hanlon, M. Topinka (UCD Dublin), P. Kubanek (FZU AV CR Prague), report on behalf of a large collaboration: We imaged the field of IGR J17062-6143 detected by Swift (trigger 525148) with the Watcher robotic telescope (D=40cm) located at Boyden Observatory, Bloemfontein, South Africa. The first on-target observation started 300 seconds after the BAT trigger time of 22:42:31 UT and before the earliest PROMPT observations reported in GCN 13390. The initial airmass was 1.2 and conditions were non-photometric. The initial two exposures were taken in the Clear filter and were 30 seconds long. We detect a source at the position of the UVOT source (GCN 13386) in the first image with R-band magnitude of 14.8 ± 0.3 (4-sigma) with the limiting magnitude in the frame being 15.6 mag (2-sigma upper limit). In the second image the source is not detected, but the limiting magnitude is 15.1. These results are not sufficient to confirm fading behavior as seen at later times by PROMPT (GCN 13390) and GROND (ATEL 4214). Later images obtained by Watcher are being analysed. Magnitudes were estimated using the nearby USNO-B1 stars as references and are not corrected for galactic dust extinction.
