Abstract	For as long as X-ray astronomy exists, X-ray (and gamma-ray) astronomers consider the Crab supernova remnant to be a steady standard candle suitable as a calibration source. INTEGRAL has been observing the Crab, for mainly calibration purposes, only about twice per year, for a total of about 4 revolutions per AO. Further observations have been sparse, and only every now and then it was in the field of view during a few ad-hoc observations of relatively nearby sources. We propose to monitor the Crab more frequently, on a regular basis. The objectives are two-fold: 1) monitor and seek for accompanying flares which have been seen at >100 MeV by Fermi and Agile, 2) improve on the (cross-) calibration of the INTEGRAL instruments, as well as with other high-energy instruments. We propose to look at the Crab every 4th revolution with a single standard 5x5 pattern for 45 ksec. The data will be made public immediately.

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.
