For the first time I in almost 30 years, a total solar eclipse will be visible in the US on August 21. The total event will be completed by 2:24 p.m., lasting a total of two hours and 47 minutes. David Baron, science reporter and author of "American Eclipse", said. Shannon Schmoll, director of the Abrams Planetarium at Michigan State University, explains why and how it happens, and what we can learn from an eclipse. When I heard about it I automatically said, "I'm going".
Free eclipse glasses are also being handed out for free at local libraries where supplies last.
Of course eclipse viewers there will miss out on seeing the sun's corona shooting out from the edge of the moon, but at least it'll still get dark and creepy outside. The Smokies are among 20 National Park sites that will experience the total solar eclipse, from sections of the Blue Ridge Parkway in North Carolina to Wyoming's Grand Tetons. As the moon passes by the sun, the moon completely blocks the sunlight in an area of total eclipse and blocks a portion of the sun's light in areas of partial eclipse.
It is very unusual that the moon and the sun just happen to be at the right distances and sizes to appear to have the same size in our sky. "The reason is because the orbital plane of the Earth around the sun is actually not in line with the orbital plane of the moon around the Earth", he says. Destinations in the path of the August 21 eclipse, which will be visible in the US along a narrow path from OR to SC, are going wild with plans for festivals, concerts and viewing parties. Check the weather of your intended destination before you spend hours sitting in eclipse traffic.
It is a bad idea to try to get to the path of totality on the day of the eclipse since traffic might be heavy and slow, causing delays beyond the time of totality. And solar filters are available for telescopes, which allow viewers to see sun flares, sun spots and the outer layers of the sun safely. Most cameras, and even many camera phones, have adjustable exposures, which can help you darken or lighten your image during the tricky eclipse lighting. It will be billed as a partial solar eclipse for Monroe County.
"People need to remember that ordinary sunglasses, even very dark ones, are not safe for looking at the sun", adds Dr. Kenneth Knudtson. A person would not know until he or she looks away and is left with permanent central vision loss. Otherwise, use an indirect method such as looking at the sun's shadow through a pinhole. With your back to the sun, look at your hands' shadow on the ground.
The spaces between the leaves of deciduous trees act as mini-projectors of the eclipse. The SDSU Society of Physics Students will host a campus viewing session near the west entrance to the Student Union Aug. 21 and will have free eclipse glasses available at that location starting the morning of the event. Tennessee's transportation department warned that it is prohibited to stop on interstates to watch the eclipse, especially in emergency lanes.
"It's a big event". I ordered some from @amazon & apparently they shipped from China & won't make it in time. Oregon's Department of Transportation said the eclipse will cause "the biggest traffic event in OR history" as visitors descend on the state in cars and camper vans. Those who have seen totality say it changes you, humbles you before the cosmos. It had "Snakes", "Science" and "Space" in it. Astronomers now study this by creating an artificial eclipse with a mask built into special instruments on telescopes called coronagraphs. Oregon is first to see the total solar eclipse and is expected to have the best prospects for clear skies, excepting the Oregon Coast.
Approximately 1 million people are expected to travel to OR for the eclipse.
The closer to the center of the path of totality, the longer totality will last. As far as how long maximum coverage will last, that will be about three minutes at best anywhere in the United States. "Please be sure to keep your headlights on for your safety throughout the entire day of the eclipse". I'm just going to do it. "My wife thinks I'm nuts", Hamill said.
