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 surrounding material close to the black holeas well as to the connection of the inflowing and the outflowing material in disks winds and jets. We have identified the Seyfert galaxy NGC 2110 one of the brightest AGN at hard X-rays as an ideal laboratory to investigate both issues through its multi wavelength variability. On one hand variable absorption has been measured in the past in the form of partial covering material.On the other hand NGC 2110 might represent a transition object between a radio quiet and a radio-loud galaxy. Variability has been observed at 8.4 GHz with the VLA (with decrease of ~40% in flux over 7 years).Here we propose to observe NGC2110 with INTEGRAL for 860 ks followed-up by Swift(XRT) and VLBA observations with the main aim of characterizing for the first time the absorption variability over days timescales and test the connection between the X-ray and radio emission lookingfor possible multi frequency time lags.
