For the first time in 100 years, the solar eclipse Monday will cover the entire U.S. coast to coast. But it's not the first time people studied it.

Thanks to the Franklin County Historical Society, we're showing you a picture of a noted astronomer and historian Coyote Bill. He visited Pasco to view a solar eclipse that was visible in May 1900. This is from the Ralph Smith collection.

According to timeanddate.com, there were three partial solar eclipses between 1900 and 1910, but they were small compared to the viewing band we will see Monday. It's expected to be 96% in the Tri-Cities.
