Clouds could obscure the view of the solar eclipse for several regions on 8/21/17

Clouds could obscure the view of the solar eclipse for several regions on 8/21/17

Monday, Aug. 21 - Join them for an eclipse viewing event. The first one may be visible from Louisville although it is more like to be seen in the totality areas and close to the total eclipse areas.

No peeking, for example, without eclipse glasses or other certified filters except during the two minutes or so when the moon completely blots out the sun, called totality. The partial eclipse starts around 11:41 a.m. This year, for the first time since February 1979, states in the USA will experience what is known as a total solar eclipse, or a "totality event".

I don't believe that George Michael and Elton John collaborated on this song with this eclipse in mind, but I guess you never know.

The totality - meaning complete darkness - only reaches some cities because the geometry of the Earth and moon and how the moon's shadow moves at a constant rate. But Carbondale will see its second total solar eclipse in April 2024. The times listed are set to the local time zone of the area the icon is over, and each icon shows what the Sun will look like at maximum eclipse for each location.

I have not seen any reports about ionospheric scintillation observations during eclipse (I might have missed them).

Astrophysicists will also be on site and so will News 2's eclipse expert, Janet Ivey from "Janet's Planet".

Just before totality, at the rim of the sun, a crescent of sunlight becomes broken by mountains on the edge of the moon - the so-called Baily's beads.

The moon is about 400 times smaller than the sun.

He still has vision in his left eye. Staff will pass out free solar eclipse glasses but there is a limited amount of seats.

Here's how NASA describes the indirect pinhole method: "Cross the outstretched, slightly open fingers of one hand over the outstretched, slightly open fingers of the other, creating a waffle pattern".

While everyone is looking at the sun, we'll be looking at you as you take in this once-in-a-lifetime event.

Mariana Lazarova, an assistant professor of physics and astronomy at the University of Nebraska at Kearney, appreciates the opportunities that come with a solar eclipse.

"The real glasses look very similar to movie theater 3-D glasses and can be purchased for as little as $2", said Steve Bernas, president and CEO of Better Business Bureau of Chicago and Northern Illinois. During a partial solar eclipse, the sun is not almost as bright, so the temptation is to stare at the sun for too long a time.

"It's a big event". In any given place, a total eclipse happens only once every hundred years or so. Only during totality is it safe to look directly at the eclipse with the naked eye.

You mean as far as indirect viewing? "It's a chance to experience space science without having to leave home". Yes, "Total Eclipse of the Heart" was obviously on it. My teacher told me I would have to wait 40 years to see a total eclipse in England. Stars also can appear.

If there are only a few small breaks in the clouds, it's going to take good timing in order to see the eclipse when it peeks through, or the ability to be mobile, to get somewhere where the skies may be more clear. Before getting into the finer details of what causes an eclipse and where the path of totality (also known as a full solar eclipse) will fall, it's important to know how to view the incredible event without literally burning out your eyes. My students, colleagues and I, with support from the National Science Foundation and the National Geographic Society, are bringing some two tons of equipment to OR to capture as much data in our computers and cameras as possible in our two minutes of totality.
