Tens of millions of people in the United States will be able to witness a Total Solar Eclipse on Monday as the rare astronomical event cuts a path from Texas to Maine, up to 122 miles wide in some spots. This is a great opportunity to see the exact moment when the moon fully blocks the sun, creating a blazing corona visible to those observing from the center line of totality.

There are a number of national park units within the eclipse path that runs from Texas to Maine that offer good vantage points to view the eclipse. And the parks offer a great Plan B of exploration and education if the day turns out to be cloudy or worse.

This week, the Traveler's Lynn Riddick, who is planning to be in the center line of totality as the eclipse passes through Texas, speaks with renowned astronomer Tyler Nordgren – who is also planning to be in the center line as it passes through New York. Lynn and Tyler will discuss the eclipse as well as some national park eclipse viewing opportunities after this break.
