Solar eclipse
When I was young, there was also an eclipse. We were told to never look directly at it even with special glasses on. We had a paper with a hole in it that showed the shadow onto another piece of paper. Is there something different today?

You can buy cheap solar vjew glasses for safe viewing. I bought 30 pair at my local Walmart for my little sister's middle school class.
Here is a link to an eclipse time lapse simulation for my town. You can change the location to your lo location. Pinch outnon the screen to enlarge and set to 60x. https://eclipse2024.org/eclipse-simulator/2024/index.html?city_id=32858 |

My friend works in Emerg, there was an internal memo from the local ophthalmologist that basically said 'if people damage their eyes looking at the eclipse, do NOT send them to me, there is NOTHING we can do'.
Get some appropriate glasses if you want to watch. It is theoretically perfectly safe to look with the naked eye during the full overlap. I won't be risking it. |
When it's not yet complete, you need special glasses. BEWARE OF CHEAP INADEQUATE FAKES. When the eclipse is complete you can look.
Or that's how I understand it. I have a filter for my camera, several pairs of glasses, and a pair of eclipse specific binoculars from the last partial that hit Texas a few years back. |

If you are in the actual path of totality, it is 100% safe to look straight up DURING TOTALITY. Not before, not after, not right as the Sun starts to reappear. When the Sun is totally blocked it is...total blocked. So, you can look up. You NEED to look up, because you can see the Sun's atmosphere then, as well as 3 or 4 planets and possible a comet. |

Thank you for the link. We in West Central Ohio are right smack in the middle of the totality. |

Late 70s we had an eclipse and we looked through welding helmets at work. Was not that exciting to me. Supposed to last around 4 minutes this time. Lots of people coming to southern Indiana for the event. I will sit on the porch and wait for the darkness.

A total eclipse is MUCH better than a partial. If you get a chance to see it, it's worthwhile. It's that eerie.

Cloud-out for TX/OK? I'm cool with that. Mrs mjohnson is still hoping to do the 14h each-way-if-no-traffic from here in NM to see the totality. As awesome as an eclipse is, I'm not ready to deal with the mayhem. I've seen two. One was from a ship in the gulf of CA in '91 and one was NW of Scotsbluff NE in '17. The one on the plains was a massive traffic "experience". I can't imagine something closer to larger populations... The sad think is that it seems like this is the last in a little surge of them -- it may be some years/decades until we see more in the USA. And yes, of course we'll be with the hordes, and likely out of gas somewhere on I40... |
any rectangular box, pinhole 3/4 up towards the open top and a piece of white paper taped on the opposite end.
point the pinhole towards the sun. cheap alternative to looking thru something. |

Our ship's room keys back in '91 for the big Hawaii-Brazil eclipse were the physical "punch-card" things. As in, holes in a pattern on a piece of plastic. Waiting for totality, we'd amuse ourselves by projecting little "suns" onto everything. (ok, we were 15-16yo) |
Is it more damaging for the eyes to look at an eclipse than to look at the sun without eclipse?
If that is the case I’d like to understand why. I have looked at the sun before, and my eyes are just fine… |

I'm going to take a guess here. I looked at the sun as a kid. I was squinting (it was bright) and I suspect kid eyes will stop down to allow very little light in through very small pupils. Also, if you look a the sun, it's normally only for a very short period quick glance. I suspect as an adult our pupils won't contract as small as when we are young. Also, if you're watching an eclipse, you're likely to look at the sun for a (relatively) LONG time compared to a quick glance. Also, as an adult, our pain threshold is different than when younger. I'm sure plenty of us have been working on something, felt something (or maybe didn't even realize that we felt something) and then looked down to realize that we had blood running out of some cut or scratch or scrape, because as an adult you're thinking "yeah, I felt that, but this crap's got to get done." I think the main problem is that folks watching an eclipse are likely to look at the sun for a much longer time than someone that looks up at the sun and think's "I glanced at the sun for 0.1 second and I'm not blind." |

The Shadow of the Eclipse moves at 1600 mph. wonder what the MPG is? |
"The Shadow knows."
|
Uh, don't eat any food during the eclipse, the solar radiation is "different"...
|
I can't wait....I've got my eye protection all set.
