INTEGRAL and RXTE monitoring of XTE J1817-330: evolving through a state change?
Abstract
INTEGRAL Galactic Bulge monitoring observations (ATel #438) indicate that the X-ray transient and black-hole candidate XTE J1817-330 (ATel #714) has increased in hard X-rays (20-60 keV) compared to the observations performed on Feb 9, 2006 (ATel #731). The 20-60 keV fluxes were 46+/-2 mCrab on Feb 11 and 79+/-2 mCrab on Feb 14. The 60-150 keV fluxes did not show a significant increase: they were 45+/-7 and 60+/-7 mCrab, respectively, on the above quoted days.
