What will the sky look like in your city during August’s rare total solar eclipse?

This is the first total solar eclipse to cross the U.S. from coast to coast in 99 years. It starts at 1:15 PM EDT in Oregon and ends in South Carolina at 2:45 EDT. It happens on Monday, Aug. 21. It will be visible to anyone within 200 miles of its path. Looking straight at the sun can blind you. Use safety glasses.

It's the final countdown to the first total solar eclipse to cross the country coast to coast in nearly 100 years.

Space junkies all over the country are gearing up for the Aug. 21 solar spectacle. If you're trying to figure out if you'll be able to catch the phenomenon from your backyard or if you need to plan a road trip, this eclipse simulator tool created by scientists at the University of California, Berkeley and Google shows you what the sky will look like wherever you are.

All you have to do is type in your hometown or zip code and the simulator will tell you how much of the sun will be blocked by the moon, how the sun will travel across the sky over a 3-hour period on Aug. 21 and what time to watch.

In Atlanta, viewers will notice a partial eclipse around 2:36 p.m., but will have to travel to witness the total eclipse in person.

“There are lots of online animations of the 2017 eclipse, but you can’t use them like ours to get a sense of the full experience, including your surroundings. Our simulation is closer to what one might experience in a planetarium show,” the UC Berkeley scientists said.

The tool could also help people figure out where to get the best “total solar eclipse experience,” the scientists said.

This simulator is part of the Eclipse Megamovie Project, a Google-Berkeley collaboration aimed at collecting and stitching together thousands of photos of the Aug. 21 eclipse taken by volunteer photographers around the country.

Vox also created a nifty eclipse tool, similar to Google's eclipse simulator, showing what you can expect to see in the sky on Monday, Aug. 21 based on your ZIP code.

But Vox's tool, based on data from the United States Naval Observatory and NASA, also tells you just how far you'll have to travel and in which direction to see the total solar eclipse.
