We propose to observe the Galactic microquasar 1E 1740.72942 for 80 ks, whilein the lowhard state, with EPICpn onboard XMMNewton. This observation willallow us to detect the relativistically broadened iron line recently revealed inarchival Suzaku & XMMNewton observations. Fits to this iron line will allow usto constrain the spin of the black hole and probe its relation to the presenceof large scale jets in this system.
