A predicted path of totality, where the total solar eclipse is expected to be visible, will be about 70 miles wide and it will stretch across the nation, from Salem, Oregon to Charleston, South Carolina.
Only a 70-mile section of the US falls under a path of totality, but there will be a partial eclipse in other parts of the country.
A NASA statement said the eclipse will be visible across all of North America, weather permitting. The entire two-day period will also be captured by Babak Tafreshi, a National Geographic photographer and science journalist, who will also provide a lesson on how to photograph the night sky and the total solar eclipse. They happen about once every year and a half, but since the moon's shadow is relatively small, not many people get to see them. This is the first total solar eclipse in the lower 48 states since 1979 and the first coast-to-coast eclipse since 1918.
While fascinating to witness, it's risky to look directly at an eclipse without proper protective eyewear.
Remember, sunglasses will not protect the eyes when looking directly at an eclipse. This rare event has created intense demand for airport services in these areas, and operators should expect delays to ground support, parking and possibly even approach sequencing to busier airports.
The Aug. 21 eclipse, also called the Great American Solar Eclipse, will sweep across the continental US from OR to SC along a path about 70 miles (113 kilometers) wide. If that's not enough and you want to experience the complete coverage of a totality, then you'll need to pack some bags and head north.
Rainbow Symphony's glasses are certified safe, but NASA warns there are plenty of phony glasses on the market that could be unsafe. Don't use them if they're bent, damaged or more than three years old.
Steven Case, astronomy professor and Strickler Planetarium director at Olivet Nazarene University, will be at the Kankakee Farmers' Market this Saturday from 8 a.m.to noon giving away official solar eclipse viewers from NASA.
