Morphologies of Magnetospheric Activity from the Point of View of the Medium Energy Neutral Atom (MENA) Imager on IMAGE Pollock, C.J., J.L. Burch, H.O. Funsten, J.-M. Jahn, D.J. McComas, R. Skoug, M. Wuest, The MENA imager has been operating on orbit aboard the IMAGE satellite since May of 2000, has shown itself to be highly sensitive to geomagnetic activity, and produces good quality images of magnetospheric ENAs in the energy range from 1 keV to above 30 keV. Since commencement of routine operations, several major and minor geomagnetic storms and numerous substorms have been documented. We find that the images returned depend strongly upon both geomagnetic activity and viewing geometry, owing to the unique properties of the ENA emission process. We will provide a brief overview of the MENA imager and show both summary data and detailed images from storm and substorm intervals, emphasizing where possible the morphology associated with fresh plasma injections. _______________ Presented at the Seventh Huntsville Workshop, Callaway Gardens, Georgia, U.S.A.
