It’s coming, are you ready for it? The sun and the moon are about to totally blow our minds this summer, and time is running out to get prepared for it. The Great American Solar Eclipse is happening on Aug. 21, and it’s going to be visible across the United States, from Oregon all the way to South Carolina.

This will be the first time we’ve had a total solar eclipse since 1979, and the first coast-to-coast eclipse in 99 years. Even if you’re not in the 70-mile-wide path of the total eclipse, a partial solar eclipse will be visible throughout the United States.

But it’s the path of totality where you’ll get to see the real show. In the heart of this strip, you’ll get to see total darkness for more than two minutes, and a plunge of up to 30 degrees in temperature. It’ll be an eerie feeling unlike any you’ve felt before.

“On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun. Anyone within the path of totality can see one of nature’s most awe-inspiring sights – a total solar eclipse,” the NASA statement reads. “This path, where the moon will completely cover the sun and the sun’s tenuous atmosphere – the corona – can be seen, will stretch from Lincoln Beach, Oregon to Charleston, South Carolina. Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun’s disk.”
