N2 - We report on the first broadband (1-200keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011 March 22, about two weeks after the source discovery. The source had an average absorbed 1-200keV flux of about 8 × 10 -10 erg cm-2 s-1. We extracted a precise X-ray position of IGR J17177-3656, αJ2000 = 17h17 m4262, δJ2000 = -36°56′045 (90% uncertainty of 06). We also report Swift, near-infrared, and quasi-simultaneous radio follow-up observations. With the multi-wavelength information at hand, we propose IGR J17177-3656 is a low-mass X-ray binary, seen at high inclination, probably hosting a black hole.
