Wait till people who are rearranging their lives for the SPECTACLE of TOTALITY find out that it lasts only 2:40 tops. I'll take the 90% over an hour or so from the comfort of my yard!

Spoke to a few eclipse chasers and they put it this way to me. "It's like going to the Super Bowl but watching from the parking lot" or "You get 5 out of 6 numbers the lottery."

So yes, you may be able to see the shadow of the moon crossing the sun with correct glasses but you will not have the life changing experience that EVERY person I have spoken to that been in totality speaks of.

Got copy/paste figured out, I see?

You already said all that.

Not exactly. Be sure the eclipse glasses meet the relatively new ISO safety standard, ISO 12312-2 (sometimes written as ISO 12312-2:2015).

Here is a reference from AAS, the American Astronomical Society: https://eclipse.aas.org/eye-safety/iso-certification

I hope more people think like you so I don't have to deal with bad traffic on the road. I don't think the partial you can see in Raleigh will be anything like totality, but I figure it's a once in a lifetime event for me I might as well go in 100%.

Conversely, it shows our kids that it is important to take time out to see the wonders of the universe. If spending time in the mountains to see this is a rearrangement of life....hell, that's an arrangement I can deal with! Especially since it is so close to us.

I went to Morehead Planetarium earlier this afternoon to get my eclipse glasses and decided to go to one of the shows that was playing there - ironically they devoted the first part of the show to talking about the eclipse event coming on. The guy giving the show explained that while we're getting a 93% eclipse event here, the 7% of the sun remaining is still so bright that it won't be 93% of an eclipse event - you really won't feel the difference other than it might feel like it's getting a little overcast and your eyes will adjust to it pretty well that you won't tell the difference (vs. complete darkness for 2:40 if you are in the path of totality). Probably still cool to get to observe the moon passing over the sun if you do stay here. If you stick around until 2075 (?) that will be the next time a total eclipse path of totality will pass over the Triangle.

He also comedically said that the last time there was a solar eclipse in the US, the majority of the eye injuries as a result of people looking at the sun without glasses were by males under 20 years old (they recovered their eyesight months later which would suck) so if you have kids........if they listen

Hope no one has to pee in that 2.5 minutes window

J/K I truly hope everyone who makes special arrangements gets to see it, the weather cooperates and the roads are not too horrendous. If I'm here for the next one I'll be on the news for world's oldest lady but my kids have a shot at it - they'll be 75 and 72.

I got these:

The article says the glasses "should have ISO 12312-2 printed on them." I think that would be excessive as the document is 11 pages. Having words to the effect "meets ISO 12312-2" should suffice.
These do have the "conforms to" statement, but then again, there is no guarantee. I have gone outside and looked at the sun and I can still see.** The image is disappointingly tiny, about the size of the full Moon. (duh?) If you have big bucks go for binoculars. I bought a filter for my 35:1 zoom camera in hopes I can get pictures.

** "YMMV"

You will not be able to tell when it happens from your back yard. Do get glasses, though.
