Abstract The source is a famous nearby (z = 0.07) blazar that has been in very high state since last summer. Astronomer Telegram n. 14069 and 14072 report large X-ray and gamma-ray outbursts seen with Swift/XRT and Fermi/LAT, respectively, that are the brightest ever observed for this source since launch of the missions. Its a historical unprecedented state. It is very bright also in optical/UV. It would be critical if INTEGRAL IBIS could observe the hard X-ray tail of the bright X-ray spectrum and monitor it at another 2-3 epochs if it is found to be bright.

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.
