IGR J17497-2821: a new hard X-ray transient detected by INTEGRAL.
Abstract
During the INTEGRAL Key Programme observations of the Galactic Centre region, the IBIS/ISGRI telescope detected the new hard X-ray transient IGR J17497-2821 at the position ra = 267.4277, dec = -28.3443. The source brightened above 25 mCrab (20-40 keV flux averaged over ~40 minutes) starting from 2006-09-17T00:35 (UTC), reaching 40 mCrab at the end of the revolution (2006-09-18T14:54). The source varies on time scales of less than one hour and is also detected above 40 keV.
