Abstract We propose fixed-time observations of the galactic microquasar SS433during two consecutive INTEGRAL orbits (240 ks + 240 ks) around the orbital hard X-ray eclipse at the disk precessional phase$\Psi\approx 0.2$ of the source in March 2013. The main scientific goal of new observations is to investigate hard X-ray flux variations before and after the X-ray eclipse to investigate disk nutation effects, discovered by previousINTEGRAL observations which were carried out at the maximum disk opening angle, at different precession phases of the source. The observations will also be used to search for spectralchanges with precession phase. The results will allow us to put stringent constraints on physical parameters of the funnel of supercritical accretion disk and hot scattering corona discovered by INTEGRAL in SS433, a unique feature of SS433 among other galactic microquasars. The proposal is not associated with any of the AO10 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.
