 At work we went outside and checked it out. It did cool off quite a bit and my buddy's girlfriend called him and said their chickens did their evening routine and went to the roost  :D.
It didn't get near as dark as I was expecting but it was neat to get to be able to see.
We looked for something with holes in it to cast a shadow, found a piece of steel with holes in it. Not the best pic but you can see the crescent shapes.

We have planned to be in St Louis to babysit our 20 month old grandson and made a big event of it with our son in law. This was the first time I've actually witnessed totality and was very impressed. I never fail to be amazed at this incredible world in which we live.

We survived the eclipse  ;D

Do you have proof?

I may be wrong. I am lobster red sunburnt with a white stripe across my eyes.  :D

I used my welding hood,number 11 glass with a pair of sunglasses which was probably about 12 total or more .Worked fine .

My parents drove up to their place in Franklin, N.C. to view the eclipse.  My mother kept me updated with texts and then later my dad sent a much longer one that I took a screen shot (3) to share with any who care to read it.  I found it amusing.

  

  

  

 

My mother reported that cicadas got cranked up as the eclipse began and when it got totally dark where they were the coyotes started howling.  In Lakeland, where I live, it got a little cooler and noticeably dimmer.  I took a few pics through my welding hood but they did not show what I could see when looking through protective lenses.

Nice nap break here, hey if it's dark time to sleep. :D
Retired to the ranch, saw, and sell solar pumps.

Grouch, those pictures of the crescent shaped shadows are interesting.

I had forgotten about shadows like that and doubted my eyes for a while.

Is this caused by changing from a disc light source to a crescent one, or is it more like a pinhole effect, by the leaves, and those shadows are actually projected images of the eclipse? The latter doesn't seem very likely, to me.

I'm 13 miles west of Franklin and we got totality.  Sitting in the sun, watching the eclipse through our special glasses. And then suddenly... it was dark! So very cool!   Had to use flash to get the second picture. 



Go to work?  Probably Knott.  Because I cant.

My inlaws and I watched it and the first thing noticed was the temp change then my wife and I were walking back to the vet clinic she works at and saw the exact shadows you pictured Grouch, I was wondering the same.  We were probably around 98%  ???  It is an eerie darkness but just got dark enough to make the street lights turn on here.

We parked at the parking lot of South Carolina University Stadium, had clear skies for the totality.

Had a good view of the diamond ring and a great view of the corona, which was larger than I expected. I noticed the shadow waves before totality as well, and sun set colors all around the horizon. Pretty amazing sight.  Even saw a bat fly out.

Then we sat in traffic for 8 hours.

I like your photos, 50 Acre Jim.   :)

Here we had 80%, and it was dim enough at 2:45 PM that my portulaca, closed and stayed closed until this morning.  You know you are living life on the wild side, when flowers closing is the highlight of your day.

We were going to watch through a welding helmet, but my Amish neighbor showed up to ask if he could borrow it, "for the children."  No way I could say no after seeing the excitement on their faces.

Deb and I drove up to a friends house in Boaz Ky. to see the darkness.  It was our first chance to see one.  It was on the bucket list, so we got that done.  The lady whose house we were out, son came in for the event as well and he brought a drone. He flew the drone up and it hovered and videoed here back yard while it was going on.   I got a video of it on my phone from where he on line, but cant get it on the forum.  I tried last night.  All those who have been around here for a while know how difficult tech. stuff is for me.  If I get somebody here that can do it I will post the video the drone made.  He put it in time lasp so it only takes about 10 seconds to see it go form light to dark and back to light again.  I can usually get pictures on the forum straight from my phone, but when I went to get the video, I couldn't find it.  When I just want to look at it on the phone its right there.  Oh well.  Banjo

Unfortunately, a lot of people decided it was safe to take off their viewing glasses during totality when only the corona was visible. Big mistake.

Most of the visible light from the sun comes from the surface. If we look directly at it the light overloads our vision systems and it feels very uncomfortable. So we don't look.

There is much less visible light in the corona so with the surface of the sun blocked by the moon, it doesn't make us feel uncomfortable looking at the corona. However, the corona is where most of the sun's UV comes from.

Since the retina has no pain sensors, looking directly at the corona for more than 1/4 second or so won't feel uncomfortable but it will do a lot of permanent damage.

Symptoms to watch for:
- washed out colour. Things that usually look like they are brightly coloured will look much paler than you expect.
- trouble focusing on things. Looking directly at the corona burns small spots on the retina so things don't look entirely clear no matter how much your eyes try to focus on them.

The good news -- small amounts of damage can heal over time. The bad news -- some of the damage will be permanent. Exposing the eye to intense UV will also lead to cataracts later in life.

Re: welding glass.  What I read in various places is that welding (at 1-3 ft) produces a greater amount of light and much more UV than the sun.  I have weld-burns that I think prove that. ::)  The internet (that I read) stated you needed at least shade 12 but 14 would be better.  The weld shop by me "said" they sold over 2,000 lenses in the last 2 weeks.  They only had 11s left.  Since my two helmets had 10s (one was pitted), I picked up a pair of 11s and used those.

We drove up Saturday to Catfish Junction on the Snake River in Oregon (9 hour drive (80mph limit for more than half the drive)) and camped with some internet friends.  Had a great time.  We were about 99.9% totality - about 15 miles south of the center but still had 2 minutes+ of darkness.  Will try to get my son's video of the darkness descending.

The temperature started dropping at about 25%, the wind picked up and it was great.  The shadows became very sharp - like someone set the contrast up to max.  Did not expect it to get so cold (about 15° drop in temp).  Everyone started howling when it went totally dark.

As seen through someone's fancy telescope.  After the eclipse we could see some really cool sunspots!

  

Totality!  This was taken by my son with his cheap Nikon point and shoot:

  

Sign after the eclipse:

 

We (my son and I) both agreed that driving 460 miles was worth it but probably wouldn't do it again.  The eclipse that is going to occur in 7 years is supposed to go from Mexico to Maine.  Then in 2054 another is supposed to do a route from the south west to the north east.  Not sure if I will be around for that one!

We had an eclipse nut (this was his 5th - they occur about every 18 months) next to us in camp - he drove out (because he had family) from Ontario Canada.  He said at the last one he went to, a woman had witnessed 23!!! :o

NASA proclaimed it safe to view the eclipse during the short time of totality with the naked eye. They also warned that anyone outside the track of totality should NOT view it with the naked eye.

Is it true that you should not look at the sun even during a total solar eclipse?
Quote
There is a misunderstanding being circulated that during a total solar eclipse when the moon has fully blocked the light from the sun, that there are still harmful 'rays' that can injure your eyes.  This is completely false. When the bright photosphere of the sun is completely covered, only the faint light from the corona is visible, and this radiation is too weak to have any harmful effects on the human retina. 
The misunderstanding comes about because of using the general term 'solar eclipse' to describe both the total phase when the sun disk is completely blocked, and the minutes before and after totality when there is still some of the sun's disk visible. It is harmful to view even a sliver of the sun disk because of its intensity, and so to simply say that you should not view a solar eclipse is rather inaccurate.

The rest of NASA's eclipse FAQ is still available at this time.

We gazed in Idaho, and it was glorious.  Loved all the schlock surrounding the event.
