INTEGRAL ISGRI 20–60 keV significance map in Galactic coordinates for Rev-1986 (MJD 58340.661-58341.806) of the sky region showing the new hard X-ray transient IGR J17591−2342, indicated by an arrow near (l, b) = (6,0), at a significance of ∼13.8σ. Other detected hard X-ray sources during this period are indicated as well among them, IGR J17503−2636, which was detected for the first time in JEM-X data during the Galactic bulge observations of Rev-1986 (Chenevez et al. 2018).
