Abstract:

The third flight of the High-Resolution Coronal Imager Hi-C 2.1 occurred on May 29, 2018 the Sounding Rocket was launched from White Sands Missile Range in New Mexico. The instrument has been modified from its original configuration Hi-C 1 to observe the solar corona in a passband that peaks near 172 angstrom, and uses a new, custom-built low-noise camera. The instrument targeted Active Region 12712, and captured 78 images at a cadence of 4.4 s 185622 - 190157 UT 5 min and 35 s observing time. The image spatial resolution varies due to quasi-periodic motion blur from the rocket sharp images contain resolved features of at least 0.47 arcsec. There are coordinated observations from multiple ground- and space-based telescopes providing an unprecedented opportunity to observe the mass and energy coupling between the chromosphere and the corona. Details of the instrument and the data set are presented in this paper.
