Abstract As a follow-up of the 2 Msec observation in AO-1 and 2.5 Msecobservation in AO-2 we propose a new deep 3.4 Msec exposure of thefield of the Galactic Center which corresponds to 27% share time inthe total available for this target in AO3. Observations of the GCregion make the best use of the unique INTEGRAL capabilities andundoubtedly are the most efficient investment of its preciousobserving time. It is especially important in the study of Galacticdiffuse nuclear and positron annihilation lines. With the proposedobservation the total INTEGRAL exposure of the GC field will exceed 15Msec by the end of AO-3 which will increase the sensitivity ofINTEGRAL instruments in this very interesting region. As confirmed bythe analysis of available first ~4 Msec of the AO-1 and AO-2observations, the guaranteed science includes detailed study of thediffuse gamma-ray line and continuum emission, monitoring of Sgr A*and of dozens of X-ray binaries, study of transient phenomena. Shouldthis proposal be accepted, the data will be made available during theproprietary period to scientists of major astrophysical institutionsof Russia.

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.
