Many across North America witnessed the August 21, 2017, solar eclipse. This view of the total phase was taken by Ken Coles, Geoscience Department, in northwest Oregon.

Coles also made a video recording to time the vanishing and reappearance of the Sun. This was part of an international effort to measure the diameter of the Sun using the known diameter and distance of the Moon.August 21, 2017, solar eclipse photo by Ken Coles
