On August 21, the moon's shadow will block the sun from view in a total solar eclipse.
Wherever you are in the United States, you're going to want to look up, and that's OK. Every astronomer in the country will tell you to enjoy this rare opportunity. No matter what superstitions you've heard, there is no risk to your health due to simply being outside during a total solar eclipse.
But there's one thing you shouldn't do, and that's look at the sun with your naked eye.
Don't do it. Really.
The only time you can look at the sun with your naked eye is A) if you're in the path of totality, where the sun will be completely covered by the moon, and B) during those two minutes or less when the sun is completely covered.

Staring at the sun

Not just any welding helmet.
The lens used for arc welding are numbered.
For eclipse viewing Shade Number 14 is required.
Sold out everywhere long ago.
The Shades can be added, but if stacked total needs to be 15.
My rig uses a Shade Number 11 combined with a Shade Number 5.
But everyone doesn’t get the totality, right?
Look at post 35. There’s a map showing the path of totality.
I am disappointed with myself - going to miss the second in a row total eclipse in my life in the region, but just can’t justify the 300 mile trip starting at 3 in the morning for 58 seconds worth of totality. Plus I just found out the store and restaurant where I’d been thinking about going are closed Monday (remote area in central Oregon). Oh well, 96% obscuration back at home will still darken the sky noticeably.
Got it!
My brother lives near Portland, Tenn. They are close!
“I would never risk looking at the sun even at the moment of total occlusion. The solar corona is still very bright, and I’m not going to risk my eyesight on the say-so of some CNN writer.”
I’m not going to respond to every comment claiming retinal damage during totality but this is BS. Those who experience eye injury during an eclipse looked at the sun before or after totality, not during. The corona is no brighter than the full moon and that is only at the part closest to the solar disk. Ask any astronomer.
“How many cows, horses, dogs, lions, etc went blind because they looked up at the sun?”
None, they are smarter than that.
I have a shade 10 Pipeliner helmet and shade 5 Oxy/acetylene goggles. Some say add the two shades together and subtract 1. I should be good to go, unless it’s too dark.
I heard that shade 12 is the minimum, 13 better. NASA recommendation:

The country has lost it’s damn mind over this eclipse.
It’s a brief distraction from the screwed up world.
I trust not looking directly the most. A simple projector can be made with a cardboard box with a pin hole and a piece of aluminum foil.
Any welding helmet that lists TIG is good for UV.
I guess but the up side is that only fools will actually blind themselves. Feel sorry for kids of fools.
Aliens sighted near Hopkinsville, KY. I know. I read it online.
Illegal or extraterrestrial?
AND most self darkening hoods DO NOT GO TO 15!!!!
Either. Or. Hesitant to say...
I garnered multiple science awards in my school days, but now I know I am as ignorant as you (and quite content to be so).
Will check out the live video feeds.
“do not try and take pictures with your cell phone. You will fry the internals”
Ditto for taking photos with any camera unless you have the proper filtering lenses.
