During the total solar eclipse on August 21, skywatchers will direct most of their attention to the sun, but don't forget about the moon: Its slow progress away from Earth means these celestial events won't keep happening forever. Lunar eclipses can last for a few hours, but solar eclipses may last only a few minutes. He says eclipse glasses have a special filter on them making them more powerful against the sun's UV rays.

The Decatur Public Library will have a solar eclipse viewing party August 21, starting at noon.

If you plan on looking up at the upcoming total solar eclipse, sunglasses won't cut it. Heading into the home stretch, it's important to reiterate SAFETY, describe what we will be doing at the Rockwall County Library, and explain why it's important to view this eclipse around knowledgeable, well-equipped people. Check with your local school, library or astronomy group to see if there will be any eclipse glasses distributed for free near you.

Since Northeast Wisconsin is NORTH of the track of totality, the maximum eclipse will look like this diagram courtesy of the Jet Propulsion Laboratory/NASA.

So the first item on the casual photographer's eclipse checklist is a certified safe filter.

On Mon., Aug. 21, millions of Americans are expected to watch a total solar eclipse, a natural phenomenon that hasn't been seen in the continental United States in 38 years.

They pointed out that even if they may dim the effects of the Sun, they don't necessarily protect the eyes from other parts of the electromagnetic spectrum. "But now the marketplace is being flooded by counterfeit eclipse glasses that are labeled as if they're ISO-compliant when in fact they are not". The ISO has also been working with gas pipeline companies, utilities and generators to procure additional reserve and regulation capacity, both of which will be needed to grapple with the potential for oversupply and frequency regulation issues after the eclipse, as solar rapidly ramps up its output.

A total solar eclipse hasn't darkened skies above the contiguous US since 1979, so if you can check it out, do so.

Florida is not in the path of totality, where the moon will completely overtake the sun and complete darkness will reign for more than two minutes. Here's what you need to know. Those who want to see the partial eclipse in real time can take part in the viewing outside the library. That means that despite being very different in size (the Moon with a diameter of about 3500 km and the Sun a diameter of about 1.4-million kilometres), they look the same size in the sky. Well, consider that seeing even a 99 percent partial eclipse versus totality is like nearly winning the lottery versus winning the lottery.
