First Image of a Sunspot from the Daniel K. Inouye Solar Telescope

via NSO

The world’s largest solar observatory, the U.S. National Science Foundation’s Daniel K. Inouye Solar Telescope, just released its first image of a sunspot. Although the telescope is still in the final phases of completion, the image is an indication of how the telescope’s advanced optics and four-meter primary mirror will give scientists the best view of the Sun from Earth throughout the next solar cycle.

The image, taken January 28, 2020, is not the same naked eye sunspot currently visible on the Sun. This sunspot image accompanies a new paper by Dr. Thomas Rimmele and his team. Rimmele is the associate director at NSF’s National Solar Observatory (NSO), the organization responsible for building and operating the Inouye Solar Telescope. The paper is the first in a series of Inouye-related articles featured in Solar Physics. The paper details the optics, mechanical systems, instruments, operational plans and scientific objectives of the Inouye Solar Telescope. Solar Physics will publish the remaining papers in early 2021.
