We propose extbf{fixed-time} observations of the galactic microquasar SS433with atotal duration of 500 ks centered at the middle of the orbital hard X-ray eclipse at the disk precessional phase$Psiapprox -0.1$ of the source in November 2014. The proposal is the continuation of the set of INTEGRAL observations of the unique galactic source SS433 carried out in previous AOs.The main scientific goal of new observations is to investigate hard X-ray flux variations before and after the X-ray eclipse to investigate disk nutation effects discovered by previousINTEGRAL observations. These observations will also add to search for long-saught spectralchanges across the primary eclipse. The results will be used to understand the physics of supercritical accretion disk and hot scattering corona discovered by INTEGRAL in SS433 a unique feature of SS433 among other galactic microquasars. The proposal is not associated with any of the AO11 Key Programs. [truncated! Please see actual data for full text]
