Abstract We propose target of opportunity observations (TOO) of a major radio/hard X-ray flare of the relativistic jet source Cyg X-3. These observations will provide an opportunity to use INTEGRALs unique capabilities to explore the hard X-ray/Gamma-ray emission. which occurs during jet production in this system. We present evidence for the production of highly relativitic jets that have a corresponding hard X-ray/Gamma-ray emission. The proposed observations will allow us to examine the nature of this emission and possibly detect the presence of annihilation lines. Additional, if lines are detected and have Doppler shifts, we can directly measure the speed of the important step towards solving the problem of what jets are made of.

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.
