Pioneer Library System to focus on solar eclipse

12 August 2017

Those within the path will be treated one of nature's most awesome events, a total solar eclipse.

Despite that it is an event lasting less than a minute here, the solar eclipse could be this summer's big event.

On Aug. 21 millions of people will look skyward as day turns into night when the first coast-to-coast solar eclipse in almost a century passes over Middle Tennessee. There is a narrow band, which extends from Salem, Oregon to Charleston, South Carolina, where observers will experience a total eclipse. It will start in Texas and go in a northeast direction, through OH and up into Canada.

Sedlacek is traveling with friends to southern Kentucky, along the Tennessee border, to capture the eclipse in its totality. August 21, weather permitting, is a don't-miss opportunity.

Though Chicago is expected to see only a partial eclipse, with 87 percent of the sun covered, it will be the closest the city has been to the path of totality since 1925. The path of total shadow will be 60 miles wide.

NASA photographer Bill Ingalls recommends focusing on the human experience of watching the eclipse. At maximum, a sliver of light will remain in the upper left corner of the sun. The sky will take on an eerie grayish, dim glow.

With the date of the total solar eclipse approaching, public libaries have been hosting special programs over the last couple of weeks, and some are also providing eclipse glasses to the public.

Staring at the sun without proper filtration, even when it is partially obscured by the moon during an eclipse, can damage or destroy photo-receptor cells of the eye's retina, leaving blind spots in a person's field of vision, experts said.

Shadow bands: Immediately before and after the, look for shadow bands on the ground and other surfaces. This only happens about every 6 months, such as August 2017 when the moon is on the line of nodes.

Blair said the moon will begin to cover the sun around 1:03 p.m.

There's a very good reason that it's hard for us to gauge the impact of the eclipse: We just aren't accustomed to it.

The moon is about 400 times smaller than the sun. Do not remove them while looking at the sun. During that time, the otherwise hidden solar corona - the sun's outer atmosphere - will become visible. Under normal conditions, the corona can not be seen from the ground because it is overwhelmed by the brightness of the sun's main disk, the photosphere. That's the sign that you need to avert your eyes.

It will help protect not only your eyes, but also the sensors inside the camera. Sunglasses are not sufficient.

One orbit later, the station will cross the path of the eclipse in the extreme northwest following a trajectory that will carry the lab over central Canada on the way to the North Atlantic. The optical device concentrates the sun's light, which can damage the solar viewer and then your eyes. This injury can occur without the viewer being immediately aware of it and it is permanent.

On Friday, we went looking. Because if you think about it, you look up at the moon in the sky and you say, 'Well, where is it gonna be? These should not be used in conjunction with any magnifying instruments such as telescopes or binoculars, since those will intensify the sunlight and can cause the goggles to break from the intense heat. They usually consist of cardboard frames (more expensive ones are made of sturdier plastic) that hold a Mylar or, more typically, black polymer material that filters out harmful solar rays. Viewing glasses will be availabe while supplies last, as well a materials to make a pin hole viewer.
