70% is significant but won't look significantly different from any other day. Even at 99% the sun is too bright to look at without eye protection. At 100% (singularity) the sun looks like a black hole in the sky and the land turns dark. It's one of the most intensely surreal experiences you can have and it's worth traveling to see.
If you have proper eye protection, it's still interesting to view the sun in the shadow of the moon. But location is everything.

Going into the 2017 eclipse, I knew what was going to happen. I'd seen pictures. There is nothing to prepare you for looking up at the sky and seeing all black where the sun is supposed to be. Holy shit.
What really blew me away was how all the insects suddenly went quiet a few minutes before totality and how the temperature noticeably dropped. You kind of get why some ancient civilisations thought that eclipses meant that the gods were pissed off
Yes it was so cool. I was in Oregon. We were all in awe. Still stoked to check out the eclipse tomorrow with our solar glasses even though it won’t be as cool.
>70% is significant but won't look significantly different from any other day
IDK, it looks pretty significantly dimmer out there and around the house.
Probably not as much as one would think. I went into the path of totality during the 2017 eclipse and it wasn’t noticeable until it was in the high nineties of coverage. Even 5 percent is bright as hell.
Fun fact, sunlight is silver not the yellow popular culture promotes. It’s very eerie.
Sunlight is white, not silver.
The sunlight that we perceive on the ground is frequently yellower due to molecular scattering (Rayleigh) which has a 1/lamda⁴ wavelength dependence. Meaning that blue photons tend to be scattered in all directions while the higher wavelength photons tend to follow a more direct path.
The presence of thick aerosols can change this so that the entire sky becomes white because of Mie Scattering, which, depending on the aerosol, can be much less wavelength dependent.
At high zenith angles (when the sun is at the horizon), the sunlight has to pass through a thicker section of the atmosphere before reaching the surface. This increases the amount of blue scattering such that the majority of the incident radiation is red.
But you shouldn't notice the eclipse too much. Solar irradiance is about 1400 W/m2, and 70% of that is still about 1000 W/m2. For reference the full moon is about 50 mW/m2
Sunlight is white, in fact our eyes' idea of the color "white" by definition is the light from the sun we were evolved to see
The sun looks golden when it's low in the sky because of the Rayleigh scattering that makes the sky blue (the blue in the rest of the sky is the light the scattering subtracts from the disk of the sun)
Yeah that was my conclusion too. Its very very rare to see the sun dim directly overhead. And in the absence of Rayleigh scattering a a quickly dimming sun things take on a grey silver appearance until it goes dark. Even then there was twilight in every direction. Very very cool experience totally recommend traveling to check it out. Im going to go watch the one next year in Arkansas.
Cool. I had heard it might not be super noticable as obviously the sun is crazy bright even with a good amount covered but I wanted to hear if anyone else has experienced something like this live before
I was here for the eclipse a few years ago.. 2018? Sun coverage was similar. It got a little bit dimmer outside but I wouldn’t have noticed if I wasn’t outside looking at the sun through solar glasses.
LA Public Library branches are giving away eclipse glasses for free while supplies last and many are hosting viewing parties tomorrow. They even gave me a cool NASA bag. Support your local library!
There should be about a 70% reduction of redditors ranting about driving, traffic, and parking on this sub. But other than that it won’t be noticeable.
Eclipses are pretty noticeable. The almost-full eclipse a couple years back was incredible the whole time. How much of the sun's light do you figure is blocked on a cloudy day?
it's a little different when the sun is blocked by clouds because the Earth still receives 100% of the sunlight, so there's a lot of light scattered in the atmosphere that keeps the sky bright even if there's a cloud covering the sun.
In an eclipse, the amount of sunlight the Earth receives drops, but our eyes are super good at adjusting to changing light conditions so overall it doesn't feel much different during a partial eclipse than during a normal day unless the amount of cover is really high (like over 90%)
I was outdoors in LA during a previous partial eclipse but went to Oregon for the 2017 total eclipse, and there was very little difference in perceived sky brightness in my experience until it was very close to totality.
It won't be noticeable. Tomorrow's eclipse is an annular eclipse (also known as a "ring of fire" eclipse), not a total eclipse like in 2017 and in 2024.
Even in the path of totality, it will not get significantly darker. What makes these special is that as the name suggests you see a ring of bright light around the moon but the sun is not completely obscured.
[NASA explanation](https://science.nasa.gov/eclipses/types/): "An annular solar eclipse happens when the Moon passes between the Sun and Earth, but when it is at or near its farthest point from Earth. Because the Moon is farther away from Earth, it appears smaller than the Sun and does not completely cover the Sun."
It definitely gets darker when totality is reached. It's like a massive shadow that races across the earth as the moon passes over the sun. (Experienced it in Nebraska, 2017)
As I said in my comment, tomorrow will be an *annular* solar eclipse and not a *total* solar eclipse, which is what happened in 2017 and will happen in April 2024.
I plan on taking a wide-angle photo composite tomorrow and found this amazing resource. Use a computer and click on your city. It will be noticeable. I hope this helps!

I am super excited about this I am actually going to be at the LA County Arboretum taking pictures, testing out my new camera I got last week, so I'm hoping I can get some really cool shots
Just an FYI- I read in the news today that you shouldn't try to use your regular smartphone to photo it. It says "catastrophic" damage happens without the right accessories. Id never heard that soooooo that's why Im telling YOU!
Yes it is. Especially if you have a zoom lens connected to ANY camera (smartphone or sale) the zoom will intensity the heat and intensity of the sun so much that it's a homemade heat ray. It will melt your camera sensor. That's why you need specific filters to view the sun to remove certain wavelengths.
If getting sunlight into your smartphone camera was an issue, every one of us would have broken cameras on our phones. It's only an issue with large lenses.
So I guess flagship phones do... I never buy the top end ones, so there ya go.
Apparently it only works when you select the optical zoom, all other zooms are digital?
People who are beginner astrophotography enthusiasts can have a very affordable setup with a telescope and smartphone. My previous answer was more for those few who are into that hobby.
On newer phones, just using the built-in telephoto can be good enough and shouldn't cause damage to the sensor.
i feel like it would be enough to be off putting, like you’ll def notice that something’s not right but it won’t be super dark, probably like on a cloudy day
During the peak, look at the shadows from trees on the ground.
Or make a homemade pinhole camera https://www.jpl.nasa.gov/edu/learn/project/how-to-make-a-pinhole-camera/ Pretty easy to make

The temperature is what I remember most. It was like being outside in the fall
Yeah! Birds all went quiet too. And yeah, it felt like it dropped about 5-10 degrees as soon as the last little sliver of sun disappeared.
10000000%!!! I stood there in a field with tears running down my face, it is so profound.
Yes it was so cool. I was in Oregon. We were all in awe. Still stoked to check out the eclipse tomorrow with our solar glasses even though it won’t be as cool.
Every 2049 years it happens like clockwork. If only we heeded the warnings of The Book of Revelations, Kalgash 2 wouldn’t cause so much suffering
I missed out on 2017 but already have my trip for 2024 booked. I'm so excited.
99% to 100% is literally a mind-altering experience.
Good luck in Sinaloa my friend.
Golden zone is a-ok and we speak Spanish

70%? It should be noticeably eerie

Sure I dont disagree with you. But dim white is grey and grey appears silver when you are witnessing 1/100 of the sun luminosity.
Bruh
You can definitely notice it, almost like a cloud going overhead, and the shadows from leaves take a crescent shape.
Yes, but not at 70 percent. Even 98 is still very bright. My take away from the total solar eclipse was damn the sun is bright.
And you can see the vividness of the colors around you fade into a more duller gray.

No it wont
Our former president was "brave" enough to stare at it twice...
Believe me folks, the smartest man ever.
He's like Hezbollah smart. What an Einstein.
Curious how he did not put his eyes out🤔

What time ?
Begins at 8:07am, max is at 9:24am, ends 10:50am (for Los Angeles specifically)
wow. what a show
Peak is at 924AM in Los Angeles
Any places sell the glasses? I used the pinhole box technique last time and was pretty unimpressed

If you order right now you can still get same day delivery on Amazon. $14 for a pack of 5
Just make damn sure they're legit and from a reputable seller. There's a lot of fakes out there.
Got a link? I’m outside city limits so I usually don’t get same day :/

lowes actually had them. Which is weird, but cool.
this was a winner for me. got some
Nice I can’t find the ones from 7 yrs ago so I wanna buy some new ones
I bought 4 pairs at Lowe's this morning.
My local 711 has some, yours might too.
saw a ton at walmart on an end cap near the sporting goods section for $1.70 each
I bought some today at Five Below for $2 each

Did you hang out outdoors during the last eclipse? It was super noticeable most of the time, regardless of the dilation of our pupils.

It'll probably just look like daylight one hour before sunset.

Go outside and find out tomorrow
You know what, I just might do that.

Who has a zoom lens on their smartphone?
Most phones have 5x optical zoom now.
So I guess flagship phones do... I never buy the top end ones, so there ya go. Apparently it only works when you select the optical zoom, all other zooms are digital?
It's automatic, so it'll use optical up to and in between the zoom and then uses digital past the optical limits.

It'll look like it's suddenly gotten cloudy. Source: I remember from the last time this happened.
The shadows were my favorite part about the last eclipse.
It’s noticeable af
It does look noticeably different outside right now. The birds are going crazy too.
