Abstract	The black hole X-ray binary GRS1915+105 (1915) has been in outburst since 1992. 1915 is the first micro-quasar that showed relativistic super-luminal radio ejections (Mirabel+1994) and it is known for its X-ray variability states (Belloni+1999) and the clear disk:jet coupling. We hereby ask for 90ks of INTEGRAL observing time, to be scheduled overlapping with the 45ks XMM-Newton TOO, in order to probe the high-energy emission of 1915. Only XMM-Newton and INTEGRAL are able to provide the long, uninterrupted observations necessary to probe the X-ray emission of GRS1915+105 on hourly time-scales. Our main goal is to probe the accretion flow in this unusual accretion state through broad-band spectroscopy of the source, which will also potentially offer new insights into the properties of accretion disc and of possible outflows.

Mission Description	The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
