Abstract	The structure and energetics of the innermost regions of black holes are still matter of debate. In particular a lot of the attention is given to the understanding of the radiative mechanisms in coronal plasma around the black hole, as well as its connection to the accretion disk and the outflowing material in winds and jets. We have identified the NLSy1 Mkn 110 as an ideal laboratory to investigate both issues through its multi wavelength variability. On one hand, an energy-dependent delay between the hard and the soft X-ray emission on few minutes to one hour scale has been discovered in this source and it has been modeled in terms of Comptonization in a hot plasma within 10 R_S from the black hole. On the other hand, this source is one of the most variable X-ray AGN in the RXTE sample on time scales of months to years, with similar variability also observed in the 8.4 GHz VLA radio light curve (with a peak to peak variability amplitude of ~ 60%), suggesting a connection between the inflow and the outflow. Here we propose to observe Mkn 110 with INTEGRAL for 980 ks, followed-up by Swift(XRT) and VLBA observations with the main aim of looking for possible multi frequency time lags.

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.
