The unexpected "ribbon" of enhanced ENA emission seen by NASA's Interstellar Boundary EXplorer (IBEX) appears to be related to the orientation of the interstellar magnetic field in the vicinity of the heliosphere. We have previously shown, using simulations of the global heliosphere, that "secondary" energetic neutral atoms (ENAs), created outside the heliopause from pick-up ions (PUIs) generated by "primary" ENAs (those of supersonic or subsonic SW origin) that have exited the heliosphere, can explain many of the features of the ribbon seen in the IBEX data. We now present our latest results that suggest that the interstellar magnetic field should be weaker than some recent simulation have assumed in order for our model to match the shape of the observed ribbon. We also show the orientations of interstellar magnetic that best match the ribbon for different field strengths, under the secondary ENA assumption.
