Across North America, millions interrupted their Monday to experience the solar eclipse, whether through pinhole cameras, solar glasses or filtered cameras.
Across a 110-kilometre-wide band of totality – and further on either side – people witnessed the skies darken and felt the temperature drop as the moon passed between the Earth and the Sun.
Here's a round-up of some of the best pictures taken to mark North America's first total eclipse since 1979.
There were, of course, the classic shots of a crescent-shaped sun:

The solar eclipse causes the shadows to do eclipses. Hundreds of eclipses. #KOMOnews #EclipseSolar2017 #eclipse17 pic.twitter.com/74HPI257CS

Even some famous names stepped out for the occasion.
While busy New York streets came to a near standstill.
Back in Vancouver, which experienced 86 per cent totality, thousands of people attended viewing parties at Science World and the H.R. Macmillan Space Centre.
