Abstract We propose to conduct \textbf{fixed-time} uninterrupted observations (163+235=398 ks) of the galactic microquasar SS433 in the primary orbital eclipse immediately after the face-on disk precessional phase of the source in September 2008}. The main goal is to obtain hard X-ray spectroscopy of the egress from the primary orbital eclipse and to study its highly variable form. The phase-resolved spectroscopy is crucial to study the structure and physical parameters of a 20 keV rarefied corona at the center of the supercritical accretion disk in SS433 discoverd in previous INTEGRAL observations. The form of the eclipse is also needed to constrain binary mass ratio in this system, which is still controversial. The proposal is not associated with the AO-6 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.
