As a follow-up of our earlier observations (2 Ms scheduled in AO-1, 2.5 Ms in AO-2, 2 Ms in AO-3, 1.6 Ms in AO-14, 1.6 Ms in AO-15, 2.0 Ms in AO-16, 1.6 Ms in AO-17) we propose a new deep 1.6 Msec exposure of the Galactic Center (GC) field which corresponds to 15% share time in the total available for this target in AO-18. Observations of the GC region make the best use of the unique INTEGRAL capabilities and undoubtedly are the most efficient investment of its precious observing time. The main objectives of the proposed observations are the monitoring of Sgr A* and three dozens of black-hole or other peculiar X-ray binaries, including a search for new transient sources and phenomena.

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.
