COSIE

COSIE (for Coronal Spectrographic Imager in the EUV) is a proposed imager and spectrograph to view the Solar corona in the extreme ultraviolet (EUV). The spectrograph would be a slitless imaging spectrometer, aiming to produce "movies" of two frames per minute, each frame, in effect, a data cube with a spectral energy distribution for each pixel. This would be done by collecting multiple simultaneous 2D spectrums (multiple orders), with spectral and spatial data overlapping twice a minute, with post-processing to untangle the resulting data to produce tidy data cubes. This approach is means of capturing a spatial image, over time, with a SED for each pixel, showing the corona's observed structure and constant changes, and is a current strategy in observation of the corona. The plan is to deploy COSIE on the International Space Station (ISS).
