About a decade ago first 3D MHD numerical simulations of the interaction of the solar wind with the magnetized interstellar plasma showed that the oblique local interstellar magnetic field (LIMF) introduces asymmetries in the heliospheric boundary. Since then, more and more observations confirm these predictions, offering a unique opportunity to uncover the strength and orientation of the LIMF. Using asymmetries observed in the spatial distribution of the Ly-α emission far from the Sun, tet{bpr2000} first reported the detection of the bow shock and its deflection from upwind. It was an opportunity to estimate the direction of the unknown interstellar magnetic field to be ˜ 40° from upwind. This result now is checked with our 3D magnetohydrodynamic model with a constant flux of neutral particles. Our new analysis confirms our previous finding for the B_{is} orientation. We compare our results with other recently reported observations.
