Abstract SS 433 is a galactic superaccreting binary with relativistic jets.Previously performed numerous X-ray observations of this source left main important topics undiscovered. Neither the compact object type and mass nor the jet acceleration mechanizm is known.We propose to obtain the hard X-ray and gamma spectrum of SS 433 with INTEGRAL, with attempt to trace the variation of the spectrum with precession phase and in eclipses.This hard emission might be produced in the lower region of the jet, according to mostmodels of the jets.The expected scientific output of the proposed observation is clarification of jet formation and emission model, and possible putting more strict limits on the compact object nature.

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.
