What will the eclipse really look like in Cheyenne? We have the answer to that question thanks to an amazing simulator. Cheyenne will see a fairly dark shade. In fact, you might be surprised how similar it looks to Casper.

The eclipse will just be a few minutes later at 11:45 am and just under Casper’s length of totality. Get the preview here, with animation checked against NASA. That's eerily accurate to the space agency's calculations. There's a look at the "peak eclipse" happening in any given spot. Just put in a city, from from Cheyenne to Chugwater, or from Denver, CO to Denver, Iowa and even Denver City, Texas. Of course, any place in the Lone Star State will stay a little brighter, but Texans will see a little moon shade.

Note two slight differences from the real thing. From anywhere here on the "eclipse map," the moon is shown approaching, but we won’t actually see it on Monday until we notice a black orb obscuring the sun. So, if you’re okay with that, you probably don’t mind the moon shown with a slight illumination of craters, which we won’t see either.

This just makes you want to say, "Thanks technology."  Have fun with it.
