Abstract

The low-mass X-ray binary Swift J1858.6-0814 has been in outburst since 2018 October 25 (MJD 58416; Krimm et al. ATel #12151). The source had a consistently hard X-ray spectrum, with a strong neutral iron K-alpha emission line, prominent X-ray variability and evidence for intrinsic absorption, and has been in this active state for more than a year (ATel #12158, #12220, #12512, #13255).
