We ask for the continuation of the INTEGRAL Key Programme observations of the area of the Galaxy bounded by -20 <= l <= +20 and -15 <= b <= +15 with a total of 2 Msec of observations per AO. The aim is to study the inner region of the Galaxy, including the hard X-ray variability of Sgr A*. and to enable significant serendipitous science in the Galactic center region. We do not ask for data rights for any of the sources, except for the Galactic Center.

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.
