SunCET: The Sun Coronal Ejection Tracker Concept

It contains a wide field of view (0–4 R) imager and a 1 à spectral-resolution-irradiance spectrograph spanning 170–340 à . It leverages new detector technology to read out different areas of the detector with different integration times, resulting in what we call "simultaneous high dynamic range", as opposed to the traditional high dynamic range camera technique of subsequent full-frame images that are then combined in post-processing.

This allows us to image the bright solar disk with short integration time, the middle corona with a long integration time, and the spectra with their own, independent integration time. Thus, SunCET does not require the use of an opaque or filtered occulter. SunCET is also compact – ~15 15 10 cm in volume – making it an ideal instrument for a CubeSat or a small, complementary addition to a larger mission.
