The ultraviolet telescope EIT of the SOHO solar observatory shows the Sun in the 304 nm range. The solar observatory SOHO is a spacecraft designed to observe the Sun, launched on December 2, 1995, and placed at the Earth-Sun Lagrange point L1. Created by NASA in collaboration with ESA, it began operations in May 1996.
The spacecraft has 12 instruments for imaging and measuring solar radiation. One of them is the Extreme Ultraviolet Imaging Telescope (EIT), which shows the Sun in different ultraviolet ranges. This camera displays the Sun in the 304 nm ultraviolet range.
