Solar Eclipse of the sun August 21st

Science Corner – Total eclipse of the sun Michael AlbrowThursday

As thousands of people travel to SC to watch the historic eclipse, the hunt is on for protective lenses to view the phenomenon. There's another good chance to see a total eclipse in Oklahoma on April 8, 2024.

The August 21 eclipse will cross the United States in about an hour and a half.

However, a majority of the sun will be covered no matter where you live across the state on Monday, Aug. 21. It will start in Texas and go in a northeast direction, through OH and up into Canada. At that time, there weren't solar eclipse glasses for him to wear to look up.

"Some 200 plus of our membership will be there, weather permitting", he said. Astronomers are calling this one the "Great American Eclipse". The path is only about 70 miles wide, stretching from OR to SC, and you will only experience a total eclipse if you're inside of it. That's going to last in this area maybe 1 to 2 minutes. At maximum, a sliver of light will remain in the upper left corner of the sun.

The sudden, albeit brief, transformation from day into night has elicited odd behavior in animals in the past. The sky will take on an eerie grayish, dim glow. Stars will shine in the middle of the day. "The little spaces between your fingers will project a grid of small images on the ground, showing the sun as a crescent during the partial phases of the eclipse".

And guess what: You can't hold binoculars or other magnifying devices over your eclipse glasses, either. At 6:20 a.m., about one-third of the sun's disk will be blocked by the moon. The moon often passes slightly higher or lower than the sun in its orbit.

The U.S. space agency suggests that "rather than trying to photograph the eclipse itself, concentrate on what people around you are doing, but perhaps with the eclipsing sun in the field of view too". In other words, they are not in a straight line. "The last total eclipse was 1979 (in Hawaii), so I don't know if historical data can be modeled". Because the eclipse will only be partial, it's essential that anyone wishing to view it obtain the correct protective eyeware. They will measure the temperature of the outer atmosphere (corona), a vast region of super-heated gas. Because the Sun is roughly four hundred times the size of the Moon, but is four hundred times farther away from the Earth, nature has set up the ideal coincidence-when conditions are just right, the Moon passing between Earth and our star causes a full eclipse of the Sun's radiant light. They will analyze the solar wind, which is particles moving out from the sun.

How can I look at it safely? Before and after totality, eye protection is necessary for anyone in the narrow path of totality.

The brief flash of light on the edge of the sun and moon that appears in the seconds before and after totality. An eye care specialist will be able to determine the level of damage upon examination, he said. This injury can occur without the viewer being immediately aware of it and it is permanent.

"We have no idea how many observations we are going to get, but we'll take as many as we can", Ricard said.

So what will the sun look like your proper glasses?

The above map shows the start, peak and end times of the eclipse, across the country. But even a small piece of the sun is sending out unsafe ultraviolet light.

And, they warn that you should never look at the sun through an unfiltered camera, telescope, binoculars. Only use a telescope or binoculars if they are fitted with reliable solar filters created to fit directly on the instruments and the operator knows how to use them.

In Madison on Friday, the glasses were sold out at Kirkland's on the Far East Side and at Toys R Us on the Far West Side. Many organizations will be providing these cardboard-framed glasses free of charge.

A spokesperson from Amazon says there's still a wide selection of glasses available. You could make your own pinhole projector to project the eclipse as a shadow on any flat surface.

Don't miss this eclipse.
