Constraint Details

Monitor: Y

Criteria: Swift will observe for the coming 5 days, INTEGRAL will observe at least until October 16th, when XMM will also point at the target. We would like to have a NICER observation per day, if possible, for the coming week, to monitor the evolution of the source, and to cross check the data which will be collected by the other X-ray missions, especially for what concerns the fast time-variability.
