Scientific paper

Here we present an innovative use of AIA data, utilizing diffraction and dispersion artifacts to preform imaging spectroscopy with AIA. Using this technique, we probe the time and spatial dependence of emission measure distributions in a compact flare. This is achieved through comparison of AIA dispersion spectra to EVE and CHIANTI spectra. In this way, we can no only probe the original spectral components of the flare emission but we can achieve this with the cadence and spatial resolution of AIA. To further extend the dataset, RHESSI spectral results are included and, in a break from tradition, RHESSI images are used to place AIA spectra in context. Unlike traditional spectroscopic methods, imaging spectroscopy with AIA allows us to capture the highly dynamic nature of flares with no compromise for spatial resolution or cadence.
