X-ray brightening and softening of SWIFT J174510.8-262411
Abstract
The sky field around the hard X-ray transient Swift J174510.8-26241 (GCN #13774, #13775) was intensively observed with INTEGRAL on Sept. 12-15 - a couple of days before its discovery. The observations were carried out under our program of studying the Galactic hard X-ray background. The 3-sigma upper limit for the flux from this source was estimated to be 0.75 mCrab in the 20-60 keV band. No any hard X-ray flares or other transient phenomena were detected.
