Abstract	The stars in the massive colliding wind LBV binary eta Car are approaching periastron passage which is associated with strong X-ray brightening and X-ray variability. NICER detected an X-ray brightening event from Eta Car starting on Nov 15 2019 (ATEL 13327) and now AGILE reports a brightening at energies > 100 MeV (ATEL 13329). A connection between the X-ray and gamma-ray variations of the source has not been seen before and needs to be studied with INTEGRAL.

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.
