HAO Colloquium - Sabrina Savage, MSFC

The NASA/MSFC Solar Instrumentaton Program with a Preview of First Results from Hi-C 2.1

The NASA Marshall Space Flight Center solar instrumenta6on group manages and develops several projects designed to improve upon observations that are currently available to the solar community. The Sounding Rocket program is an active constituent of this effort beginning with the flight of the Solar Ultraviolet Magnetograph (SUMI 1) in 2010 up to the most recent flight of the High-resolution Coronal Imager (Hi-C 2.1) in May, 2018. The Hi-C instruments are designed to address the fact that the spatial and temporal resolutions of the available coronal observatories are inadequate to resolve signatures of coronal heating. High-resolution and high-cadence observations available with the Interface Region Imaging Spectrograph (IRIS) and the High-resolution Coronal Imager (Hi-C) instrument hint that ~0.3 arcsec resolution images and < 10 s cadence provide the necessary resolution to detect heating events. The first flight of Hi-C took place at White Sands Missile Range on July 11, 2012 and obtained images of a solar active region in the 19.3 nm passband. For Hi-C 2.1, the mirrors were recoated to observe in the 17.2 nm passband and the science goals were focused on acquiring co-temporal and co-spatial observations with IRIS. These data provide a unique method of testing the energy flow between the chromosphere and corona. I will present an overview of the MSFC Solar Instrumentation Program and a preview of the performance from this latest flight of the Hi-C rocket in conjunction with the coordinated data sets (Hinode, IRIS, SDO, and ground-based observatories) in anticipation of a full release of results and data products to the broader solar community in the coming months.
