Abstract:
The Sun Coronal Ejection Tracker (SunCET) 6U CubeSat mission completed its Phase A concept study late this year and is now under review for down-select. The design of SunCET is driven specifically to observe the middle corona: a wide FOV (0-4 Rs) and simultaneous high dynamic range (HDR) detector make this possible without the need for occulters or filters to dim the bright solar disk. SunCET’s driving science question is: “what are the dominant physical mechanisms for CME acceleration as a function of altitude and time?” The majority of CME acceleration occurs in the middle corona, which is a historically underobserved region due to the technological difficulties in measuring this region and the fact that prior mission tradeoffs were driven by other science objectives. I will present a mission overview, examples of the data SunCET will provide, and the types of constraints those observations represent for various CME models.
