Who Can See It

Lots of people! Everyone in the contiguous United States, in fact, everyone in North America plus parts of the Caribbean, Central America, and Europe will see at least a partial solar eclipse.

What is It?

This celestial event is a solar eclipse in which the moon passes between the sun and Earth and blocks all or part of the sun for up to an hour and a half, from beginning to end, as viewed from a given location. 

Where Can You See It?

You can see a partial eclipse, where the moon covers only a part of the sun, anywhere in North America (see "Who can see it?"). To see a total eclipse, where the moon fully covers the sun for a short few minutes, you must be in the path of totality. The path of totality is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from Southwest to Northesast.

When Can You See It?

Times for partial and total phases of the eclipse vary depending on your location. This interactive maps will show you times for the partial and total eclipse anywhere in the world. l

How Can You See It?

You never want to look directly at the sun without appropriate protection except during totality.  That could severely hurt your eyes.  However, there are numerous safe ways to view an eclipse.  Click here for eclipse viewing techniques and safety.

Finding Experts to Volunteer at Your Event

We encourage you to seek out local experts for your public events.  Many astronomy enthusiasts plan to travel to the path of totality, but many will be staying closer to home, so please check out all of these different resources to find experts near you:  

Affordable Eclipse Glasses

An eclipse is a rare and striking phenomenon you won't want to miss, but you must carefully follow safety procedures. It is vital that you protect your eyes at all times. The only safe way to look directly at the uneclipsed or partially eclipsed Sun is through special-purpose solar filters, such as eclipse glasses or handheld solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are NOT safe for looking at the Sun. To date, only three manufacturers have certified that their eclipse glasses and hand-held solar viewers meet the standards for such products.
