One of the most active areas in black hole research currently is understanding the role of jets in the overall emission properties of black holes from radio all the way to gamma-rays. Thanks to RXTE and the daily monitoring campaigns of radio and optical/IR facilities we have gained good understanding of the relation between jet emission in the optical/Infrared (OIR) Radio and X-rays in the PCA band. Yet our understanding about jet and high energy emission is still not clear because of limited information from INTEGRAL and due to absence of dedicated reasonably long observations to investigate this relation directly. Using HEXTE on RXTE and some INTEGRAL data we clearly see the spectral breaks right before we see evidence of compact jets in radio and IR during outburst decays but we do not know how they evolve. This evolution may provide information about the conditions of launching compact jets that are ubiquitous in the low hard state of black holes. With the experience our group gained over the years we can pinpoint almost exactly the time that the compact jet forms and evolves during decays of outbursts. We therefore propose one TOO observation of a GBHT with INTEGRAL for 220 ks at the transition to the hard state as the jet turns on to investigate the relation between the X-ray emission and jet formation. We will achieve multiwavelength coverage using ATCA in radio and SMARTS in OIR. This proposal is accompanied by an accepted SWIFT proposal. The current archival data are not enough to carry out this research. [truncated! Please see actual data for full text]
