Our group has developed a pinhole Anger camera to detect and image auroral X-rays in the energy range 20 - 120 keV. We have flow this camera on four different occasions and have imaged auroral zone X-rays from dawn, dusk, and noon. The fourth flight was from a circum polar navigating balloon from Antarctica. Our data, which sampled a small number of the dynamic auroral precipitation temporal forms, show that auroral X-rays persistently include small spatial structures of approximately equals 20 km (at ionospheric heights). Our camera obtained energy spectral information as a function of space and time and shows that precipitation includes at least two energy components, one with an e-folding energy of a few keV and another with an e-folding energy of tens of keV. These X-ray images 'remote sense' the distant magnetospheric sources and indicate that there are at least two different source populations.
