The High Resolution Coronal Imager, or Hi-C, captured the highest-resolution images ever taken of the million-degree solar corona using a resolution five times higher than previous imagers.
The corona is hotter than the solar surface and is the location where solar flares occur and energy is released that drive solar storms that can impact Earth.
Weighing 464 pounds, the 6-foot-long Hi-C telescope took 165 images during its brief 620-second sounding rocket flight July 11. The telescope focused on a large active region on the sun, with some images revealing the dynamic structure of the solar atmosphere in fine detail. When combined with the full sun images from NASA’s Solar Dynamics Observatory, SDO, a new picture of the solar corona is now emerging.
