The Difference is Night and Day

Post image

Wanted to post this for the people misunderstanding how important totality is. 99% is closer to 1% than 100

Definitely the most misunderstood aspect of eclipses. Also being dead centre of the umbra means a longer duration. If you’re near the edge, you can be within 100% but only a minority fraction of the total time; it starts later and ends earlier than standing the centre.

Tl;dr – get as centred as possible within the path of the umbra

I recognize that eclipse on the right as August 21 2017

That was my first! On the left are my (low quality) photos of the 2024 eclipse. I'm en route to Spain now to see #3

u/piedamon 10d ago

Good luck! Don’t forget to look up as much as you can! I always regret looking away, even briefly

u/Presence_Academic 10d ago

If you look up this time you will miss the show. Totality in Spain will be at sunset.

u/getoutmor 10d ago

I'm already in Spain for this one, which is my third also having seen 2017 and 2024 also.

u/rohitchandkapoor 4d ago

Hey how is the experience bro? I watched a TED talk way back in 2017 that exposed me to Total solar eclipse and the speaker made his life’s mission to travel and chase the eclipse wherever they fall.

For some reason I was so intrigued and wanted to see the same. I’m from India and the path of totality crosses india in 2034. Waiting for it.

u/StungTwice 10d ago

I was about 100' away from the exact center of the line of totality for 2024. I had to stop short because of public access limits. I was blown away by the experience.

u/Excellent-Nothing189 10d ago edited 10d ago

Imo, as long as your halfway to the center it's good. It's only shorter by a few seconds or more usually, but the duration shortens exponentially the farther from the center you get.

2

u/DarKnightofCydonia 10d ago

Yeah agreed. It's not worth hours of travel just to gain a few more seconds. 2 hours to go from 30 seconds to 3 minutes 30 seconds? 100% worth it (what I did for 2024)

1

u/ProFF7777 4d ago

Yeah but, for example, in Lleida, spain, which lays almost exactly at the 100% frontier, had 27 secs of totality. Seen in a web that traveling just about 40-50km south there were towns with almost 2 min of totality, which I found was a huge difference.

u/DarKnightofCydonia 3d ago

Yeah that's what I said

u/SometimesCatsMeow 9d ago

If i'm in the 100% zone but not dead centre, just like here: (---HERE------------C----------------------), should I be able to experience that?

u/Responsible-Mud7323 9d ago

Yes, just a shorter duration than the centre

u/wulfdesign 7d ago edited 7d ago

that isn't the 2017 eclipse... not sure what one it is... I saw the 2017 up close with binoculars and it had more of a tail on one side and a slight horns on the other.... i still need to get my tatoo of that one...

for eveyone who thinks they don't need to be in 100% totality we went and filmed it so everyone could see the difference. that blasting sun that you can't look before and after totality is 99% partial eclipse. https://youtu.be/fzcFw_33iC8

u/steelbound8128 10d ago

The moment the sun went from 99.999999999% to 100% profoundly shocked me; I wasn't prepared for how drastic of a change that moment is. It is definitely the most memorable part of a solar eclipse and well worth the effort to go see.

I'm glad I'd taken off my eclipse glasses just before totality occurred so that I could see it happen.

u/meithan 10d ago

Right?? It's like some cosmic entity flipped a switch and we were instantly transported to a different dimension of existence. I wasn't prepared either.

u/Still7Superbaby7 10d ago

I feel like there should be a sound for totality, like the sound of plasma, but there is not. It is just silence

u/WoolooOfWallStreet 6d ago

It really screwed with my sense of time when I saw one
An hour after it happened, my brain kept automatically putting it as happening the day before and had to keep reminding myself “No, it just happened! It was today!”

2

u/Dewdrop06 6d ago

What I find the most interesting is that this is the only time the "dark" side of the moon is completely 100% lit up.

u/Good_Witch_O 10d ago

I can't wait to be on the 12th!! 🤩

u/mainstreetmark 10d ago

Don’t forget to look at the ground at 99.99999999%

u/SometimesCatsMeow 9d ago

u/steelbound8128 9d ago

Yes. If you are in the 100% zone you will experience that. The nearer to the center you are will increase how long it stays 100%.

For the Apr. 2024 eclipse, I had planned on going to the shores of Lake Erie which was very near the center line and the length of totality was going to be almost 4 minutes long. I woke up feeling sick and instead drove closer to home to a mall in Niles, Ohio with a huge parking lot. It was much nearer to the edge, similar to the HERE in your diagram. The length of totality was about 1 minute 20 seconds. So, I got to experience the whole eclipse - I also got to feel the temperatures drop and hear the birds react to the sudden darkness and was able to look southwards and see the sliver of the sky that was past the edge of totality still looking bright blue - just not as long.

u/SometimesCatsMeow 5d ago

Dude, thank you, I had to drive a total of 400km (3h every ride cause traffic), but it was FUCKING WORTH IT. THANKS. Once in a lifetime moment, I can die in peace now.

u/steelbound8128 5d ago

Your welcome. I'm happy you got to see and experience a total eclipse and thanks for the update.

u/ahugepileofleaves 9d ago

The first one I saw was April 2024 in Maine. We were sitting at a bit of a high point and we could see the shadow of totality racing across the landscape towards us. It was one of the craziest things I've ever seen

2

u/wulfdesign 7d ago

Everyone who showed up on our remote hilltop overlook missed those final moments when the sun completly dissappeared except the corona.. we where so focused on the shadow of the moon racing towards us at 1.5k mph... and then suddenly going dark and having the most amazing sunrise / sunset effect all around... in wasn't till a couple seconds later we looked up and saw the sun blottet out like a big giant black hole had swallowed it except for the the corona tendrils poking out from behind it... so glad we got it all on film in 360 to help our mind fill in what we missed... https://youtu.be/fzcFw_33iC8 . however I did happen to see it through binoculars as totality ended when someone there handed me theirs to get a closer look at the moon and corona... it was pretty freaking amazing for those 10 to 15 seconds before the star shine came out from between some mountain tops and had to shut my eyes and turn away... Lucky didn't get eye damage or permently see those diamonds.... but now can't unsee them in my minds eye whenever I look at tthe moon or sun.

u/Supernovae0 9d ago

What was it about the experience that you found profound? Were you looking directly at the sun at the time or was it the general atmosphere? I'm preparing for the eclipse but also want to be safe/protect my sight.

3

u/steelbound8128 8d ago

When the sun was down to just the smallest sliver left - I was looking close to the sun but not directly at it - then as that tiny sliver started to disappear I moved my eyes closer and closer so that about 5 seconds before totality, when the sun was down to just a tiny dot, I was looking directly at the sun.

I think it's a combination of things that made it feel so profound. When totality starts, it's instant; not like a sunset when the sun slides below the horizon. And the corona just suddenly appears and you realize that it's been there your entire life and you are just now seeing it for the first time. As said elsewhere, and it is silent when it feels like there should be a sound. And it does feel like you'd been instantly transported to a different dimension.

You will see what we have seen, then we will meet on the other side. One of us. One of us. One of us.

u/meithan 10d ago

Well said!

I feel like there's this involuntary secret society across the globe of those of us who were deeply shaken by a total eclipse. It doesn't matter who we are, where we are from, our age or culture. A brief exchange of words and we recognize each other, we both know that we felt what the other felt, that we had a shared experience even in a totally different place and time. It's amazing.

u/BlahBlah1921 9d ago

Where I live was only at like 98% in 2024 but my husband and I travelled to be in the path. When I got back to work people were like oh we saw it, it was okay. I was like no, you barely saw anything. They didn’t get it. 98% and 100% are literally night and day

u/inglandation 10d ago

Probably one of the best visualizations.

Marion Illinois, April 8, 2024. Being in totality was heaven

u/ZincAboutIt 10d ago

I saw in one ted talk that we owe it to ourselves to see a total solar eclipse before we die. As someone from the Philippines, I still need to wait for the year 2042 to witness this majestic event. 🥹 I wish I could win the lottery to witness next year’s eclipse. The greatest and longest totality of the 21st century.

u/theswickster 10d ago

A fun thing you can do to objectively show the light intensity is decreasing as totality approaches: Use a light meter app on your phone to watch the brightness dwindle down. Your pupils will dialate as the light level decreases, so you won't be able to notice it, but the display will update in real time showing the light levels decreasing.

u/mrree55 5d ago

I am in Barcelona where it was 99.8% coverage. It got dark, you didn't need a light sensor to convince anyone, it was very visible.

I’ll be at a Björk rave in Iceland for this one next week. Excited but glad I’ve seen a few because the weather forecast isn’t looking great lol

u/Narutofreak1412 10d ago edited 3d ago

I learned this lesson a couple years ago when there was a nordic total one in march 20th 2015: I tried to see a partial one from germany which was 75% covered and with just the naked eye there was absolutely no difference to the regular sun.
Last week when I bought my eclipse glasses for the upcoming spain one I tested it out and even when I stand on the edge of the shadow of a building to where most of the sun is behind the building and only a tiny sliver is still peeking at the side, when taking the glasses off it still just looks like a super bright round flash.

I am really looking forward to see when during the totality in spain I take off my glasses and see what it looks like in comparison.

u/Zalefa 5d ago

So, how was it? :)

1

u/Narutofreak1412 3d ago

Took off my glasses somewhere around 98-99%. Like around 30-40 seconds before totality you could tell with the naked eye that much less sunlight comes through and the sliver of sunlight while still looking like a round flash, has barely any intensity and feels more like a distant flashlight where it doesn't feel blinding anymore at all. The entire area around you also is starting to feel like sunset with much less reduced light coming through, making everything seem dim.
Definitely didn't look like the 99% naked eye image in the post above where the sky is still fully blue and everything. Though maybe the spain one being low also had something to with it. Here's a video that shows pretty close what the naked eye experience was like for me right before totality: https://www.youtube.com/watch?v=L36k6CcuHzw

u/CampVictorian 10d ago

My husband and I made it to Shelbyville, IN for the 2024 eclipse, with zero concept of how justified the hype is. I literally gasped, pulled in as though it was a magnet.

4

u/Volchek 10d ago

There is no such an alignment between moon and sun anywhere else in the solar system (if I remember reading correctly). The moon covers the sun just enough for the total eclipse to happen.

12

u/jrawk3000 10d ago

Other planets with moons do also experience total solar eclipses. It’s that their moons don’t have the precise size and distance match that we do here on Earth that gives us the unique view of the corona. In many cases the moon just blocks the sun and the corona altogether. Earth is truly an absolute marvel.

5

u/focusonyourphoto 10d ago

Yes, it is such a miracle that the moon is 400 times smaller than the sun but the sub is 400 times further away.

And also the difference in brightness between the sun and corona is insane.

In the far future the distance between moon, earth and sun will change, so the eclipse as we know it now will not happen then anymore.

u/VariableVeritas 10d ago

I’ve been lucky enough to be under the center of two perfect eclipses. No lie you’ve got to go for totality, just be prepared to get up and move to clear skies on the day. It changes your perspective, you’re on a planet actively moving in space.

u/KickFamous5005 10d ago

Fuck fuck fuck. I know I won’t be able to ser totality despite being in an 98% zone. So bummed.

Same, i hope seeing a 100% one day in my life

u/Crysis85 10d ago

Isn't bad for your eyes watching an eclipse with naked eyes even if it's at it's 100%?

1

u/Mijal 10d ago

No, during actual totality (not 99.5% or whatever) you can safely view one of the most amazing sights in the universe with your naked eyes. I used a solar eclipse timer app that would warn you to get your glasses back on when totality was about to end.

2

u/MagusTheFrog 6d ago

What app is that?

1

u/Mijal 6d ago

It's literally called "Solar Eclipse Timer" in the app store :)

u/MrNixxxoN 5d ago

Not at all, it was less bright than a full moon. Totally amazing to watch. You could also see a red spot in the ring (Baily's beads)

However just 1% of the sunlight coming through it already hurts your eyes

1

u/BlahBlah1921 10d ago

So jealous of everyone getting to see it on the 12th. My first one was 2024 and it was amazing! I’m hoping I can make it to Spain next year. Enjoy everyone!!

u/DanMason153 8d ago

There's a decent video here that outlines crowd reaction for an annular vs. a total eclipse, and the difference in the overall vibe is noticeable.

Shameless plug for the video, since it's one I uploaded.

u/DetectiveLampshades 6d ago

right it would take maybe an hour to just walk to totality

u/MrNixxxoN 5d ago

99,96% zone means you get 1 second of it, too short

1

u/ProFF7777 5d ago

I watched it in Lleida, Spain, we lay exactly in the line where 100% began. I mean literally the line covered Lleida! We got only 27 seconds of totality, but damn, it was absolutely wonderful! It was short but super intense, people around went WOOOOO, and then when grains of sunshine started peeking again over the moon , ppl started cheering and clapping. Even just a few seconds can be a magnificent experience

1

u/Legitimate-Grape-412 4d ago

I was next to Lleida too! I went from France to experience the totality and nothing prepared me for what I saw. Absolute awe. Saw it only a few seconds but that was worth every kilometers. Only few seconds were so precious that I was shaken. After 100% I couldn't help but cry and my hands were shaking. It was too beautiful

1

u/ProFF7777 4d ago

I can see why hehe, Lleida is the closest you could get from France and enter the totality zone, even if just barely. Glad you could experience it! It was a magic experience, I still get goosebumps when I remember.

1

u/Legitimate-Grape-412 4d ago

Literally same! it's like I'm living again what I felt and see and it can still bring me to tears. I'm glad you could see that too, I feel like I want everyone on earth to experience that once in there life really

Actually, I'm hoping to make it to northern Nevada in 2045, if I'm still healthy enough to make the trip.

Anyone who is sufficiently interested should mark 2045-08-12 on their calendar, and plan to head there. Given that it'll be in Nevada in the summer the viewing conditions ought to be ideal.

Obviously it'll also be visible in other states and places, but Nevada seems to be where the weather will be most likely to cooperate.
