ToO: Y
Coordinate Observation: Y
Observatory: IXPE; NUSTAR, SWIFT
Description: This source has been already observed by Nicer. Therefore an additional Nicer coverage simultaneous with already approved IXPE, Nicer, Swift DDTs is a unique opportunity to complement the polarimetric data with high resolution timing and spectral informations. The presence of XRT and Nustar data could help to quantify the eventual contribution of the nearby source AX J1745.6-2901.
Uninterrupted: N
