The science channel is making a big deal out of this. They are cool to watch but unfortunately I live about 300 miles south of the path the total eclipse will follow. I think my area will get between 50 and 75% totality.

I think that we may get 3 minutes of total darkness here in Middle Tennessee. It is said to be frightening to watch and experience.

Even so: to see the Penumbra racing along at very high speed will be an emotional realization for me I am sure.

I am still amazed that Columbus knew when an eclipse was about to take place.

I think seeing that phenomena will only be possible from the air. On the ground the event will happen at the speed of the sun crossing the sky.

Nyah, nyah! 89% totality here!

I checked and locally the coverage will be 88.3%. I doubt if you could detect a 0,7% difference. ;-)

I still remember the eclipse of 1961 because it coincided with the end of a love affair. There is a movie, I believe by Antonioni, which describes such a coincidence.

My best one was the almost total eclipse in London in 1954 aged 9, quite scary at a young age.

There is also the Saros cycle 126, repeating every 18 years, and the Metonic series every 19 years. What with the 11 year cycle of the sunspots the Solar system is a convoluted place indeed.

The sun is fixed. The Earth is rotating at 1000 miles per hour linear speed at the equator. At my latitude its about 600 miles per hour. If I could find a tall building here in Nashville, I might be able to see the darkness rolling in. I figure that the shadow is about 120 miles wide.

Back in the early 90's, I experienced a partial eclipse, and it was weird. I didn't know it was coming. I was just sitting outside on the courthouse steps where I worked, eating my lunch around noon on a clear and hot summer day, when the light outside started dimming , and the air became noticeably cooler. The dimming of the light was eerie because there wasn't a cloud in the sky, and birds started flying around like they do in the evening. Quite an interesting lunch. I'm really looking forward to this one coming up because I think Louisville, Kentucky is closer to the total path then it was last time.

Yes Gordon, I remember that event here in Nashville. It was around noon here as well and. I had a pinhole in a piece of cardboard projecting onto a sheet of white paper. I think that it got up to a 3/4 eclipse. Yes the light was quite different then. The total eclipse will be even more strange and exciting.

In 1954 we all smoked pieces of glass over candles to look at the sun. 'elf & Safety hadn't been invented then. And we had to write a piece in class mentioning that it went a bit cold for a bit as well as darker. Flipping smartyarse teachers! We didn't give a fig one way or the other, just an excuse to skip half a lesson in the playground. But it was a bit weird at the time.

It is probably also the one I experienced in south central NY in the early 90s.

I went to the planetarium today to get some special glasses, and they told me this area should experience a 96% eclipse this time. I'm kind of leery of using the glasses. I just hope it doesn't rain!

There is also a total lunar eclipse in 3 days, Aug. 7th. But none of the lunar eclipse will be visible from the USA.
