Solar eclipse watchers from OR to Idaho will likely have the best view of the August 21 event along the path of totality, based on a map created using NASA Earth satellite data.

While the full eclipse of the sun will be happening to the north in OR, the partial eclipse on display in Stockton will see the moon blocking about 75 percent of the sun.

In addition to its preparation event, the Fort Wayne Astronomical Society also will help people experience the solar eclipse by having members out from noon to 3 p.m. August 21 in the plaza outside the main library, a group news release said.

In Canada, where we'll only see a partial solar eclipse for the entire duration, this won't matter quite as much.

Nikon says that despite the fact that the moon covers the sun, the crescent that is seen around the moon is so risky that it could cause vision damage and even blindness.

"There was a time - and it wasn't that long ago, five or 10 years ago - when the basic eclipse predictions assumed that the moon was a ideal circle in the sky, and that the sun was a flawless circle in the sky".

NASA has put together a list of what size lens and an example of what you may see using each one.

"From the standpoint of seeing something that's a once-in-a-lifetime opportunity, this eclipse is still very special", Lazarova said. As the Moon slips in front of the Sun, the landscape will be bathed in long shadows, creating eerie lighting across the landscape.

The eclipse is only expected to last about two minutes, but Bart Treece with Washington's Department of Transportation says visitors from BC need to be prepared for what he describes as a "multi-day" experience.

The CVB also is working with hotels to provide solar eclipse viewing glasses, she added. Participants will learn about the science behind the solar eclipse and even take a turn riding a moon buggy.

If there are only a few small breaks in the clouds, it's going to take good timing in order to see the eclipse when it peeks through, or the ability to be mobile, to get somewhere where the skies may be more clear. Those events inspired him to pursue a career in astronomy, and today, at 65 years old, he's known as "Mr. Eclipse" for his contributions to the field.

Science Central's gift shop is selling solar eclipse viewing cards for $1.99 each to the public and for $1 each for Science Central members.

According to NASA, about 325 million people in the country will be able to view some portion of the eclipse.

Inspect solar filters before use. You can also make a nice pinhole projector inside a box, such as a large cereal box or shipping box. "For Kearney, the previous one was more than 800 years ago". I'll be talking more about it and my physics students will be doing calculations related to the eclipse and things we can figure out from it. These can easily be made by simply poking a pin-sized hole (thus the name) in a piece of cardboard, and then holding the cardboard such that the sunlight passes through the hole and falls onto a viewing surface (a white piece of paper, sidewalk, garage door, etc.) To focus the image, the observer simply moves the cardboard farther or nearer from the viewing surface.
