INTEGRAL detects hard X-ray emission from XTE J1817-330
Abstract
During the start of the third period of the INTEGRAL Galactic Bulge monitoring observations (Kuulkers et al 2005, ATel #438), the X-ray transient and black-hole candidate XTE J1817-330 (ATel #714) has been detected in the 20 - 150 keV range. The observations comprised ~7 ksec taken on 9 Feb 2006 between 09:02 and 11:43 UTC. The estimated flux seen by ISGRI in the 20-60 keV range was ~33 mCrab, which compares with an earlier measurement, on 27 Jan 2006, of 22 mCrab in the 10-30 keV band (ATel #714).
