Rush to catch "The Great American Eclipse"

On the 21st of August this year, the sun will go dark in the middle of the afternoon.

Government aircraft will be dispatched to follow the eclipse and take infrared measurements to determine the solar corona's magnetism and thermal structure.

While the path of the total eclipse is relatively narrow - less than 100 miles wide, according to Gutsch - a partial eclipse will be visible to all of North America, Central America and northern South America. "I have patients who viewed the sun 40 years ago, who remain without central vision in their affected eyes". "The general impression is, if you live somewhere with a 90% partial eclipse, that's good enough". This is more common than a total solar eclipse, but it's nothing to sniff at if this is your first eclipse.

It is the first total eclipse visible in the USA since February 26, 1979, Science Museum Oklahoma Planetarium Director Tom Arnold said.

UO particle physicist Jim Brau will be immersed in the sold-out crowds, delivering a speech on solar science at the OMSI Solar Eclipse Viewing Party in Salem, which is the first of five state capitals that the total eclipse will visit August 21.

Total and annular eclipses through 2020.

While a solar eclipse can be wonderful to behold, the phenomenon has little impact on Earth.

The Earth's energy system is in a constant dance to maintain a balance between incoming radiation from the sun and outgoing radiation from Earth to space, which scientists call the Earth's energy budget. We know this stuff, right?

Goldendale is expected 98.12 percent coverage - meaning 98.12 percent of the sun will be covered by the moon, essentially blacking out the sky.

"Because the moon is so much smaller than the earth, when its shadow falls on the earth, it's so much smaller", she said.

Roughly one million of these aspiring astronomers will do their sun-gazing in OR, parts of which are situated in the eclipse's path of totality where the moon will completely cover the sun.

Where and when will this happen? Another eclipse in August 2045 will pass directly over Colorado.

The total solar eclipse itself will begin at 1:15 p.m. (EDT) in Lincoln City, Oregon and end at 2:48 p.m. (EDT) near Charleston, South Carolina.

There will be sunspotter telescopes that project the sun's image onto paper as well as a limited number of eclipse viewers that enable people to look directly at the sun without damaging their eyes, she said.
