Movie of a Sunspot (VIDEO)
Caption
The Wave Front Correction context viewer camera at the NSF's Inouye Solar Telescope recorded this movie of a sunspot on Jan. 28, 2020. The 2000 by 2000-pixel camera captured this sequence at wavelength of 530 nanometers. The field of view is about 25 arcseconds square or about 12,000 miles across. This short movie compresses about one-and-a-half minutes of viewing into just a few seconds to highlight the significant evolution of small-scale structures known as penumbral grains and umbral dots.
