The moment of darkness is fast approaching.
The U.S. will experience its first coast-to-coast total solar eclipse since 1918 on Aug. 21. But not all Americans will see it equally.
Never miss a local story.
Most of the Sunflower State will see only a partial eclipse, where the moon covers part of the sun. More than 90 percent of the sun will be blocked out in Wichita and much of southeastern, central and northwestern Kansas.
“This is going to be a very significant amount of the sun covered up by the moon,” said Harold Henderson, Lake Afton Public Observatory director. “You’re going to noticeably tell that a big portion of the sun is covered… whether you’re using eclipse glasses or not.”
“It would get noticeably dark outside,” he added.
The partial eclipse will begin around 11:36 a.m. and end around 2:32 p.m. in Wichita, according to the National Weather Service. About 92 percent of the sun will be blocked in Wichita at the height of the eclipse, shortly after 1 p.m.
“This is just a slow progression from beginning to end,” Henderson said. “It’s not like a light switch on and off. It’s going to be a gradual thing.”
But a partial eclipse that covers 99.9 percent of the sun’s surface will still be 1,000 times brighter than a full moon, according to the Kansas City Star.
The path of totality – where a total eclipse of the sun by the moon will completely block the light – will travel diagonally across America from Oregon to South Carolina.
Only a sliver of Kansas lies in the path of totality — cities in the far northeastern corner of the state like Atchison, Hiawatha and Leavenworth.
Kansans serious about astronomy have long since booked their hotels and trips to cities and towns that lie in the path of totality. Those places are embracing, but also bracing for, the unique event attracting thousands of people, where roads and parking could be heavily clogged.
People in the path of totality will see a partial eclipse at first. But what’s special is the “last little bit of sunlight just before totality,” Henderson said.
Observers will see Baily’s Beads, which are points of light that shine around the moon’s edges. They’re caused by light rays from sun streaming through valleys along the moon’s horizon, according to NASA.
And then totality: where the moon completely blocks the sun. It will last a few seconds up to more than two minutes, depending on where you are.
During totality, you’ll be able to see “lower layers of the sun’s atmosphere streaming off into space,” Henderson said.
You will also be able to see several planets and stars during totality due to the lack of light.
“The temperature can drop...The stars come out,” said Fred Gassert of the Kansas Astronomical Observers, a Wichita-based group. “It is instant climate change for two minutes.”
Henderson has only seen static photos of total solar eclipses; the Aug. 21 eclipse will be his first.
“You’ve got this beautiful scenario,” Henderson said. “I’m really excited about experiencing totality for myself just to have some answers.”
