The complete occlusion of the Sun and the onset of darkness lasted about two minutes. The Moon covered the Sun for 1.5 hours, and the solar corona was several times larger than during other eclipses. Bright stars and planets were visible. All this could be observed on August 21, 2017. And the DKIST telescope, the most powerful solar telescope in the world, tracked solar activity during the eclipse.
The Great American Eclipse was the first solar eclipse since the founding of America (1776), whose complete phase could be observed exclusively in the United States.
The next similar eclipse will be on September 2, 2035.
