Visualization of High Latitude ion Upflow in Support of the IMAGE Mission Gordon R. Wilson (NRC, Space Science Laboratory, ES83 NASA/MSFC, Huntsville, AL 35812, 205-544-7638, e-mail: wilsong@cspar.uah.edu) Among the various magnetospheric imaging instruments that will be carried on the IMAGE spacecraft is one that is designed to image energetic neutral atoms produced by ions flowing out of the high latitude ionosphere. To date only a limited amount of work has been done to model the environment and produce synthetic images from which instrument response can be assessed. In this project I have developed a 3-dimensional model of cleft ion fountain, polar cap and auroral zone upflows. The model gives ion fluxes, as a function of position, pitch angle and energy, for H+ and O+ ions in response to changing interplanetary conditions and levels of geomagnetic activity. The ion fluxes are then converted to ENA (energetic neutral atom) fluxes using the appropriate reaction cross section and neutral hydrogen density at the given altitude. A line of sight integration code is then employed to create images for a hypothetical camera with a given angular resolution and sensitivity, from positions along the proposed IMAGE orbit. Example images for the great magnetic cloud event of October 1995 will be shown.
