The National Science Foundation’s Inouye Solar Telescope is located near the summit of Haleakalā in Maui, Hawaiʻi. On 28 January 2020, researchers used the 2k × 2k Wave Front Correction (WFC) context viewer camera at the wavelength of 530 nm to observe the first sunspot. The short movie compresses about 100 seconds of solar time into just a few seconds to highlight the significant evolution of small-scale structures known as penumbral grains and umbral dots.
