The highest resolution data from the corona we currently get on a regular basis are from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO), however, even higher resolution images have been obtained during a sounding rocket flight by the High-resolution Coronal Imager (Hi-C). The scientific objectives of Hi-C are central to the goal of understanding the Sun’s activity and its effects on the terrestrial environment by providing unprecedented views of small-scale structures in the solar atmosphere.
The Hi-C instrument is scheduled to launch on a sounding rocket May 29, 2018. This will be the third launch of the Hi-C instrument.
