Abstract The famous HMXB Vela X-1 has in recent years also be found to emit in the radio. The detection took place, by chance, while the X-ray source was in eclipse. In the coming days, there will be further radio observations (ATCA, plus MeerKat for the 2nd and 3rd) spaced out around the binary orbit to find clues on the unknown radio emission mechanism. A NuSTAR DDT has in the meantime also been approved. We would like INTEGRAL data to cover time around and covering the coordinated observations in order to enlarge the covered energy range and especially to have a better handle on the source variability, before, during and after the radio + X-ray observations. Other X-ray observatories (XMM-Newton, NICER) are visibility constrained. Some Swift coverage will be done.

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.
