:siren: attention goons who go outside, this is your 13 month warning :siren:

On Monday April 8th, 2024 a Total Solar Eclipse will grace North America for the second time in only 7 years! If you caught totality in August of 2017 then you know what the hype is about, but if you missed it this will be your last chance to see one on this continent until 2044.

Here is a map of the path of totality, overlayed on a map of typical cloud cover for April:




:frogsiren::frogsiren::frogsiren:

Since we are LESS THAN ONE WEEK away, weather forecasts are starting to get somewhat meaningful.

This website has a nice dashboard which shows four different forecast models for April 8th, automatically updated when the models update.

It also has an explanation about each model’s strengths and weaknesses. Here is the current run of the model it describes thusly “Its forecasts for cloud cover are the most nuanced and realistic available on this page”:
(Note that cloud cover is shown in blue here, clear skies in white)

I am planning to be in Mazatlan, and the hotel we’ve been eyeing there just this week opened up reservations for April ‘24 so I’m in spread-the-word mode now.

So who else is planning to travel for this one? Use this thread to share wisdom learned in 2017, or convince other goons that it is worth their time and effort to travel to the path of totality (99% is extremely NOT the same!)

I'll be somewhere in the southern part of the state, filter on my telescope, on the big day.

To reiterate how rare and unique this is, let’s ponder the fluke of cosmic history that allows us to experience a total solar eclipse.

What makes totality special is the fact that the disks of the moon and sun are almost identical in size from our perspective here on the surface of the earth. That is what lets the moon perfectly block out the sun while leaving the sun’s atmosphere (corona) safely visible to the naked eye. But this wasn’t always the case and won’t always be the case! It is a fluke of the moon’s size and distance from earth. Hundreds of millions of years ago the moon was closer to the earth and thus would have also blocked more of the corona. And about 600 million years from now the moon will be too far away from the earth to ever fully cover the sun. Total eclipses will cease to occur, replaced instead with gradually less spectacular annular eclipses.

We just happen to be alive at a time and place where the moon sometimes perfectly obscures the sun such that we can observe this beautiful interplay.

Also looking at that cloud cover map, I’d highly recommend that anyone who’s not planning to view this from Mexico have a car and a plan to drive for open skies based on the weather the night before or early that morning if need be.

Spamming this thread with some more info and resources:

So You Want To Photograph a Total Solar Eclipse
Here is a page with a lot of detail on eclipse photography, from Fred Espenak who is one of the biggest eclipse chasers out there and has many decades of experience doing this. I will excerpt some highlights here to give an idea of what's involved and drive home the general point that it is difficult and not recommended, especially if you have never seen totality before:

Fred Espenak Mr Eclipse.com posted:



Certainly the most spectacular and awe-inspiring phase of the eclipse is totality. For a few brief minutes or seconds, the Sun’s pearly white corona, red prominences, and chromosphere are visible ( The Experience of Totality). The great challenge is to obtain a set of photographs that captures these fleeting phenomena. The most important point to remember is that during the total phase, all solar filters must be removed. The corona has a surface brightness a million times fainter than the photosphere, so photographs of the corona are made without a filter. Furthermore, it is completely safe to view the totally eclipsed Sun directly with the naked eye. No filters are needed, and in fact, they would only hinder the view. The average brightness of the corona varies inversely with the distance from the Sun’s limb. The inner corona is far brighter than the outer corona; thus, no single exposure can capture its full dynamic range. The best strategy is to choose one aperture or f/number and bracket the exposures over a range of shutter speeds (i.e., 1/1000s to 1s). Rehearsing this sequence is highly recommended because great excitement accompanies totality and there is little time to think.




It should be pointed out that the exposure table above is only a guideline for planning purposes. The brightness of the corona may vary from one eclipse to the next based on the relative point in the sunspot cycle as well as the current activity on the Sun during the eclipse. Because of the high dynamic range in the brightness encompassed by the corona, there is no one single exposure that is "correct." The best strategy is to bracket widely during totality to shoot a large range of exposures. I typically shoot at ISO 200, f/9 and will use shutter speeds ranging from 1/1000 down to 1 or more seconds.


Point and Shoot Cameras
Point-and-shoot cameras with wide angle lenses are excellent for capturing the quickly changing light in the seconds before and during totality. Use a tripod or brace the camera on a wall or fence since slow shutter speeds will be needed. You should also disable or turn off your camera's electronic flash so that it does not interfere with anyone else's view of the eclipse.

Another eclipse effect that is easily captured with point-and-shoot cameras should not be overlooked. Use a straw hat or a kitchen sieve and allow its shadow to fall on a piece of white cardboard placed several feet away. The small holes act like pinhole cameras and each one projects its own image of the eclipsed Sun. The effect can also be duplicated by forming a small aperture with the fingers of one’s hands and watching the ground below. The pinhole camera effect becomes more prominent with increasing eclipse magnitude. Virtually any camera can be used to photograph the phenomenon, but automatic cameras must have their flashes turned off because this would otherwise obliterate the pinhole images.

But hey, if you already have a cool telescope with a motor drive and a fancy DSLR you can attach to it and automate, go for it!

So with it being a given that it'd be better to be inside the red lines, how cool or not would the eclipse be in Oklahoma City? It's so close to the red lines, relatively speaking. I could probably convince my wife to rent a cabin in SE Oklahoma for it, but that's :effort:
The entire show is between those red lines. Being outside them is like being a mile away from the venue where your favorite band is playing. Being inside them is like standing in the front row at the show.

You either make the effort to get to totality, or you are effectively ignoring the eclipse. There’s really no in between.

You live SO close, you’re incredibly lucky to be within a day’s drive of a total eclipse at all. Absolutely make the effort to get there. As I mentioned upthread, the next total solar eclipse in North America isn’t until 2044!

Just be aware that clouds will absolutely ruin the show.

Or just pick your spot and roll the dice, clouds are tough to predict sometimes!

In 2017 I scouted our spot on google maps (cross referenced with BLM land maps, but that part isn't really applicable for this one as there's virtually no BLM land east of the Great Plains).

My friend pointed out that maybe instead of Illinois and Ohio, we looked northeast, which is about the same drive, to like Vermont and Upstate New York, which has infinitely more protected land and also isn't Ohio, so I think I answered my own question there
Perhaps more scenic but also worse weather odds, check the cloud cover map in the OP

Just depends on your priorities and risk tolerance.

Edit: depending on where exactly you target, upstate NY could be similar cloud odds to parts of OH and IL. The other thing to be aware of is further east means eclipse happens later in the day which means lower in the sky, which means you need a larger portion of the sky to be cloud-free to see it

I skipped driving from Vancouver BC to Oregon for the 2017 eclipse because I didn't realize how rare it was to be within distance and with the correct weather conditions.

Now I'm planning to go down to Texas for 2024.

Do I just find a camp spot on the side of the road anywhere on the line? How close to the line do I have to be? Just within the dark shaded area?
If you click on this link in the OP you can zoom in an click around to see how the duration of totality changes as you get further from the centerline.

Near the Texas/Mexico border for example, being right on the centerline gets you about 4m26s of totality while being half way between centerline and the red edge gets you 3m50s. The duration falls off faster as you get closer to the edge of totality.

Thus post has some details about trying to take pics of an eclipse. As noted already, it’s probably not worth your effort unless you already have a lot of gear.

You can however use your nice camera to take some wide shots during totality that capture the landscape with the eclipse in the sky:


Especially if you’ve never seen totality before, I’d definitely recommend enjoying the moment and not fiddling with a camera.

My plan is to be in Austin proper -- we have friends we can stay with out there so we don't need to get lodging. Is there any consensus on a park or something where the viewing will be good?

Austin is near the edge of totality, so right in the middle of the city it's about 90 seconds. The airport is outside of the path. You can get about 3m30s by going maybe 30 miles east or around 2m30s by traveling 30 miles north. Round rock is ~20 miles up the highway and it's ~2m45s there.

When you're near the edge of the path, you can get a lot of additional time by just getting a little bit closer toward the centerline.

I don't know the area but it's something to consider.

The thing is in 2017 a lot of people weren’t familiar with eclipses. Millions of Americans saw it for the first time and told all their friends who missed out.

Many saw partial coverage because they didn’t know what a difference totality makes, but they found out when their friends or family came home and told them.

Just look at this thread or the Reddit sub for how many posts there are from people who saw 90%+ last time and are determined to see totality this time.

I think significantly more people will seek totality this April than did so in 2017, and traffic could be much worse.

This one does go over more major metro areas though. I’m not sure if that will make traffic better or worse, hard to say. But if your rural traffic experience in 2017 was mild, I’d say you were the exception not the rule.

From Toronto it might be worth a game-time decision if you can’t commit to a more involved mission. Keep a close eye on the weather in the days leading up to the event, if the forecast looks good the night before then get up early and make the drive in the morning.

If the weather prospects for everything within a reasonable driving distance look lovely the night before then just stay home.

I’d be prepared for a VERY slow drive back home that evening though. Ideally you could find somewhere to sleep in your car Monday night and drive home Tuesday morning.

That’s how I’d be thinking of it if I were in Toronto with a little time but not enough for a bigger trip.

Mantle posted:

If anyone is on the fence about going to the path of totality because you are hanging around the umbra, GO TO THE TOTALITY.

Having totality anywhere near where you are is on the scale of literal once-in-a-lifetime opportunity.

I decided not to drive 6 hours down to Oregon in 2017, thinking that there would be more opportunities in the future. After, I looked at the almanac and it is never coming as close to where I live in the remainder of my entire life. The next closest is this year, 2 days drive away in Texas. Some time in the coming decades, I could drive 13 hours to Alberta. On top of the distance thing, you need to have good weather, and be in the right season. All of these factors make it virtually impossible for me to see a totality without an inordinate cost.
Not sure how old you are but 2045 is a similar path to 2017 but shifted south a bit, so it will cross Northern California instead of central Oregon. Thats probably closer than Texas but also maybe we are all dead in a nuclear fireball before then.

But yeah the rarity is not so obvious at first.

This is how my dad has approached eclipse travel for the past 25 years since our first in 1999.

He keeps an eye on where they are going to be and if there’s one that coincides with a place he wants to visit anyway, he plans the vacation around it. In typical retired boomer fashion this has taken him to Egypt, South Africa, Chile/Argentina, China, Iceland, and the South Pacific among others.

But a lot of people are less interested in or able to travel the world like that so that’s why I’ve been hyping this year and did the same for 2017 to friends and anyone else who will listen.

Oct 28, 2009

As we approach the one month countdown, I was recently reminded of a very goony but effective tip for total eclipse enjoyment: wear an eye patch over one eye from the start of the partial phase until totality.

This lets the covered eye adjust to low light conditions during that time. Once totality starts and you remove the eyepatch, the dark-adjusted eye will help the other eye adapt more quickly, and overall you’ll see more of the Corona and more stars etc because your eyes would otherwise not be able to adjust to the lower light in time.

I did this in 2006 and 2017 with good results both times. Just don’t injure yourself walking around without any depth perception for an hour.

If you want to drive yourself insane we are now in the realm where weather models will make specific cloud cover predictions for April 8th. They are still changing wildly from day to day however, so not very reliable at all, yet.

bawfuls
Oct 28, 2009

I have not, but my understanding is yes. With full cloud cover you would not see the moon and the sun's corona, which are the main attractions. You'd barely notice that it got darker, you wouldn't see the 360-sunset, stars and planets, etc.

Clouds are killer and dedicated eclipse chasers will go to great lengths to find clear skies for totality. In 2017 my dad was in Jackson WY, some of the people in his group got spooked by the forecast and hit the road at midnight the night before to drive for more favorable conditions. Jackson ended up being fine but clouds are the enemy here.

bawfuls
Oct 28, 2009

I dunno, my dad was targeting Jackson for 2017 at least a decade before it happened. I think he started calling the ski resort about 5 years in advance asking when he could book a tram ride to the top for the eclipse. He had a big group of fellow eclipse nerds with him, like 40 people or something.

xzzy posted:

It's been shown to be very hard to predict numbers for eclipses, they happen so rarely that no one really has good data on them. So most agencies plan for the worst and at least for the two since 2017 attendance has been less than forecast. Oregon roads did fill up post-eclipse but that's because there was only a couple two lane roads available for use, but the state got well under the million they expected. Wyoming saw less than 200k people show up. Obviously the closer to a major population center the worse it's going to get, southern Illinois had ~300k show up in 2017. South Carolina saw many less than predicted, but they also had clouds move in so it probably pushed people away.

So I guess the lesson is plan for the worst but don't be surprised if things are just fine.
This one is much closer to a lot of major population centers than 2017 was. But maybe more importantly, tens of millions of people saw 2017 and were made aware of how amazing totality is. Those people went home and told their friends and family. Now even more people are aware than in the lead up to 2017. I would expect turnout for this one to be through the roof.

And if Texas is rained out like models are predicting, who knows how that throws other spots into chaos as some number of people try to change plans over the weekend and drive several states away.

bawfuls
Oct 28, 2009

Reminder for anyone traveling to Vermont or similar locations in the eastern end of the path, totality for you will be in mid afternoon which means the sun won't be super high in the sky. You can check the map in the OP for exact geometry at your intended location but in Vermont it will be about 40 degrees above the horizon, so don't pick a spot that is too heavily wooded, lets you block your view with trees.

Maybe this is obvious to people already there, but with the forecast the way it is now there might be some last minute eclipse chasers scouting for spots.

yeah we landed in Mazatlan this afternoon, it’s high wispy clouds and not that many

The Canadian model shows like <20% cloud cover and is allegedly the most nuanced cloud cover model. The American model tends to overestimate and shows 80% or whatever, but it also has a cloud thickness foreceast which is <20%.

High thin clouds aren’t necessarily a show stopper. We do have some people with rental cars in our group for Plan B near Durango if it comes to that but as of now I don’t expect it will be necessary. Here’s hoping!

Forecast in Mazatlan is just borderline enough to still consider driving inland. But it’s all thin high clouds here and it is not clear to me that the Durango area will be significantly better in this regard. The models show it being pretty similar and the current satellite images do as well.

Spending a total of 8+ hours in a compact rental car doesn’t sound appealing to me and it’s really not clear whether that will buy us any better conditions.
