Abstract	We propose two fixed-time observations of the galactic microquasar SS433during three full INTEGRAL orbits in April 2017 and three full INTEGRAL orbits in November 2017 with a total duration of 1.2 Ms centered at the middle of the orbital hard X-ray eclipse (orbital phase phi=0) at two cross-over disc precession phases Psi = 0.37, 0.65 of the source (INTEGRAL orbits 1804-1806 (April 12 -- April 17), and 1883-1885 (November 8 -- November 13)). The proposal is a continuation of INTEGRAL observations of the unique galactic source SS433 carried out in previous AOs.The main scientific goal of the new observations is to investigate the orbital light curve in hard X-rays at the cross-over phase (disk edge-on) in order to probe the structure and features of the supercritical accretion disc and hot scattering corona, discovered by previousINTEGRAL observations of this unique galactic microquasar.The proposal is not associated with any of the AO14 Key Programs.

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.
