Abstract The source has recently entered into outburst. We observe an increase in the radio band with a flux reaching about 10 Jy at 4.7 GHz. Moreover, Swift/Bat shows an increase in the lightcurve, the flux is more than 100 mCrab in the 15-50 keV band.With this observation, we aim to:- investigate the evolution of hard X-ray spectral shape and the relative contribution of the Comptonization and jet components to the X-ray spectra emission. - assess correlated multi-wavelength behavior across the spectral states to probe the accretion-ejection connec- tion and the contribution of the jets to the hard X-ray emission in different states. - search for mHz QPOs that have been previosly detected only in individual observations of Cyg X-3. INTEGRALs unique long observations are especially well suited for searches for such slow QPOs that at lower energies are also expected to be washed out by the Compton thick absorption in the dense wind of the companion.

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.
