Solar eclipse visible from 154 national parks Sunday

Sunday's solar eclipse will be the first visible in the US this century. The annular eclipse will be best seen from 33 national parks, including the Grand Canyon.

On Sunday, a solar eclipse – a partial disappearance of the sun behind the moon – will be best seen from the western US. Here, a partially eclipsed sun sets on Oct. 13, 2004 as seen from Waikiki, Hawaii.

When the sun vanishes behind the moon for the first time over the United States in this century, what better place to enjoy the view than from one of the 154 national parks that stand in its path?

Astronomy lovers in the United States will be treated to a partial disappearance of the sun behind the moon this Sunday (May 20). Only the Eastern Seaboard will be totally exempt. Over the course of the solar eclipse, the sun won't vanish completely, but will remain as a ring around the moon for what is known as an annular eclipse. When the eclipse occurs, the moon will be near its most distant point from Earth, making it appear smaller in the sky and thus unable to block the entire sun. But it will still be a stunning sight.

Thirty-three national parks will see the full effect of the moon's interference. Many western parks will be offering an array of events for their guests, ranging from placing telescopes out for viewing up to a full-scale astronomy festival.

"We're lucky that so many parks happen to lie within the path of the annular eclipse," Grand Canyon park ranger Marker Marshall told OurAmazingPlanet.

A grand event

The Grand Canyon park staff, along with the help of the Tucson Amateur Astronomy Association, will be setting up solar telescopes and helping people safely view the eclipse. NASA scientists will be present to talk about the eclipse, as well as recent lunar findings. They will also have eclipse glasses for sale and will demonstrate how to use binoculars to safely set up a projection of the eclipse on a piece of paper. After the eclipse, the park will host a star party. [Top 10 Most Visited National Parks]

Marshall noted that, like other national parks, the Grand Canyon boasts signs warning people not to look directly at the sun, or to view the sun through telescopes, binoculars or cameras without a solar filter. Doing so will damage your eyes.

At Bryce Canyon National Park in Utah, the annual Astronomy Festival has been moved to coincide with eclipse weekend. Great Basin National Park in Nevada will hold a pre-eclipse party Saturday night with a presentation by an actor playing Galileo, and a special program on Sunday. Several parks will instruct guests on how to make a pinhole viewer of their own to safely observe the eclipse. Several other parks are receiving assistance from their local amateur astronomy clubs to help the public safely watch the show.

Visitors should bring flashlights and jackets, especially if they plan to stay after the eclipse concludes.

"People come to parks to enjoy a dark night sky, and see things like the Milky Way," Marshall said.

"We can really facilitate people seeing even daytime events," she added.

A spectacular view

But Marshall warns that, while the eclipse will make an interesting image, it won't necessarily make a great photograph.

Aiming a camera at the eclipse unprotected could damage it. Hopeful photographers need to add a solar filter to their setup, which will wash out the view of the landscape.

"The casual photographer won't be able to get a photo of the eclipse over the canyon," she said.

Instead, she urges people to enjoy the image captured in their memory.

And there will be plenty of memories made. According to Marshall, all of the campgrounds and hotels around the Grand Canyon that take reservations are booked. Though the first-come, first-serve campgrounds are still available, she anticipates that they, too, will fill quickly, leaving hopeful visitors with a drive of more than an hour to the nearest hotel.

Although only a handful of western parks will receive the full effect of the eclipse, another 125 parks lay along the path of the partial eclipse, where they will provide a stunning view to those not fortunate enough to see the complete show. From Alaska to Minnesota, national parks will catch a partial eclipse or a partial view.

"Astronomy generally is the kind of thing people look for in national parks, so we're glad to help people celebrate it here," Marshall said.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
