There is a live broadcast on the NASA website.

On August 21, the inhabitants of the Earth will be able to observe an infrequent phenomenon - a total solar eclipse. It will not be visible on the territory of Russia, the inhabitants of the United States living on the other side of the planet will be able to observe the astronomical event with their own eyes. But this is not a reason to be sad. On the NASA website, a live broadcast of the eclipse will be conducted from several points located in the territory of its visibility.
The live broadcast will run from 19.00 to 23.00 Moscow time. The maximum phase of the eclipse can be seen at 21 hours 26 minutes.
The eclipse of August 21 has been nicknamed the "Great American", because for the first time since the formation of the United States at the end of the 18th century, it can only be observed in the United States. Strictly speaking, this was the last time before that in the 13th century, but then there were no white colonists in North America.
The shadow from the moon during this phenomenon will pass through the entire territory of the country from one ocean coast to another. In the Far Eastern regions of Russia and the most western European countries, partial phases of the eclipse will be visible, on the rest of the Earth it will not be observed at all.
In addition to ordinary people, for whom a natural phenomenon is of interest mainly as a spectacle, scientists are very interested in observing an eclipse. In those minutes when the Moon closes the Sun, dozens of specialists will observe them, studying the influence of the star on the Earth and its own structure. Among them, we note the Citizen CATE experiment - observing the eclipse using several (68 of them) telescopes of the same design and characteristics. Each of them during the eclipse, which lasts for 2 minutes 40 seconds, takes about a thousand pictures. As a result, the cumulative photographic material covers several hours of the life of the solar corona - with all the perturbations that have occurred during this time.
A similar goal was set by Amir Kaspi of the Southwestern Research Institute of Colorado, but he will solve it by different means: he suggests flying after the shadows on an airplane equipped with a telescope. It is assumed that the footage he filmed will help answer the question of how energy is transferred in the solar corona.
