The interplanetary magnetic field (IMF) at Jupiter_fs orbit is mainly in the Y-JSE direction. The Parker spiral angle is 11 degrees at the Jovian orbit (5.2 AU). In addition Jupiter has a dipole tilt of 9.8 degrees. In this paper will use a three dimensional global magnetohydrodynamic (MHD) simulation code to model the influence of IMF BY and dipole tilt on the configuration of Jupiter_fs magnetosphere and thereby extend our previous results in which we only considered the effects of IMF BZ. To simulate Jupiter_fs rapidly rotating magnetosphere with dipole tilt, IMF Bz and By we have extended our MHD model to handle the full three dimensional Jovian magnetosphere by removing the symmetry boundary condition at the equator. In this presentation we will present results with IMF BZ =XX and By=0.42nT. We used a simulation box with nearly 108 cells (600,400,400) and grid spacing of 1.5RJ. We will use the results of this simulation we to demonstrate the basic structure of Jovian magnetosphere as a function of IMF direction and dipole tilt.
