TITLE: GCN CIRCULAR NUMBER: 17071 SUBJECT: GRB 141104A: further Swift-XRT observations and afterglow candidate DATE: 14/11/17 17:00:02 GMT FROM: Valerio D'Elia at ASDC V. D'Elia (ASDC), L. Izzo (URoma/ICRA) and D. Malesani (DARK/NBI) report on behalf of the Swift-XRT team Swift-XRT has observed again a field in the error box of the IPN GRB 141104A (Hurley et al. GCN 17026). The total exposure time of the new observation, which started ~ 10 days after the IPN trigger, is 9 ks. Source #2 reported in D'Elia & Izzo (GCN 17036) is still detected with a consistent count rate, while source #1 is marginally detected at a S/N level just below 3. The count rate of the new detection clearly implies fading between the two epochs. Despite the slow temporal decay (t^-0.55) and the flux variation of a factor of just two that can not exclude another origin, source #1 is the best afterglow candidate for GRB 141104A. Further observations are Sun constrained until February 2015.
