Abstract We propose to conduct two fixed-time observations (237 ks + 150 ks) of the galactic microquasar SS433 covering the egress from the primary orbital eclipse and ingress into the following primary eclipse near the face-on disk precessional phase of the source in November 2010. The main scientific goal is to carry out hard X-ray spectroscopy of the primary eclispe ingress/egress and to study its highly variable form. The phase-resolved spectroscopy will be used to probe the structure and physical parameters of a 20 keV rarefied corona around the center of the supercritical accretion disk in SS433 discoverd in previous INTEGRAL observations. The proposal is not associated with the AO-7 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.
