Abstract We propose to conduct \textbf{fixed-time} observations for 2 uninterrupted INTEGRAL orbits (2 times 233 ks) of hard X-ray eclipse of the galactic microquasar SS433 at the maximum opening disk precessional phase, centered on May 2, 2007, 11:30 GMT, with the aim of confirming the unusual shape of theeclipse bottom first discovered by Ginga and suspected by previous INTEGRAL observations. This would allow as to put stringent constraints on the nature of hard X-ray emission region in SS433, discovered by INTEGRAL, and to independently evaluate the binary system mass ratio, which is a still unsolved controversy for this source. The proposal is not associated with the AO-4 Key Program.

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.
