Total solar eclipse 1st in 99 years to sweep width of US

How to properly watch a solar eclipse

The August 21st eclipse will be the first visible in the contiguous United States since 1979 and the first one to cross it coast to coast since 1918.

During totality and only then, NASA scientists say it's safe to look directly at the eclipse. It is aptly named the Great American Eclipse.

After starting in OR, the eclipse is expected to begin in Charleston around 1:16 p.m. before reaching totality, which will last less than two minutes, at 2:46 p.m.

A total solar eclipse comes when the moon comes between the sun and Earth, completely blocking out the sun for a few minutes at most.

BUDA PUBLIC LIBRARY will be hosting a Solar Eclipse Party on August 21st from 12:00-2:00 pm.

On that date, a total solar eclipse will plunge vast swathes of the country into an unnatural darkness lasting for nearly 2 minutes. The sun as a source of light affects our environment and that of other planets.

Pasachoff and his colleague Marcos PeƱaloza-Murillo are working to conduct standardized measurements of numerous local effects of total solar eclipses. With this method, sunlight streams through a small hole - such as a pencil hole in a piece of paper, or even the space between your fingers - onto a makeshift screen, such as a piece of paper or the ground. Regardless of the materials the frames are made of, the Mylar filters are the the important part, and observe all safety precautions while viewing the eclipse (see below).

During this national event, the shadow of the moon will sweep across the United States in a narrow band from the Pacific Ocean to the Atlantic Ocean in a spectacle that hasn't occurred in decades.

Furthermore, it affects behaviour, especially that of animals.

Understanding the sun has always been a top priority for space scientists.

"This eclipse is historic, with a huge effort underway by organizations across the country to prepare people for the experience and use this rare opportunity to teach science", said Mike Simmons, President and Founder of AWB. The Earth's atmosphere is a good insulator, meaning it doesn't exchange heat easily. The sun's constant stream of solar material and radiation can impact spacecraft, communications systems, and orbiting astronauts.

NASA has strongly cautioned against directly looking with the naked eye at the sun outside of the total eclipse window.
