What is the 2017 US Total Eclipse?



A Total Eclipse of the Sun occurs on average somewhere on Earth about once every 18 months. However, any one point on Earth will be in the path of totality on average only once every 360 years. It’s a rare event in any one locality, a once-in-a-lifetime opportunity.

On August 21, 2017, millions of people in the USA will be in the path of totality. They will experience a spectacular phenomenon; probably the most awe-inspiring light show in the world. Only people within the path of totality will witness a Total Eclipse of the Sun.


The path starts at dawn in the Pacific Ocean off the western coast of the United States. This is when the umbra first touches the Earth. It makes its first landfall in Oregon at around 10:15 am (Pacific). Covering a path around 65 miles wide, the umbra will take just over 94 minutes to cross to the East coast, leaving South Carolina at around 2:49 pm (Eastern) before hurtling out into the Atlantic Ocean.
