Analemma (3-year time-lapse)

- Time-lapse of the Sun in the West, one picture every 24 hours: the solar analemma. Watch as the Sun traces out a figure 8 in the sky each year from 2015 to 2018.
Why does the position of the Sun change day-to-day? The Earth spins about its axis at about a 23.5 degree angle to its orbital axis around the Sun, and the Earth orbits the Sun in an ellipse, moving faster when closer to the Sun. The result is that the position of the Sun in the sky changes not just minute by minute as the Earth rotates, but day to day as well as the Earth moves through its orbit. The figure 8 path traced out by the Sun when viewed in 24 hour increments is known as the solar analemma.
This video was made from a series of pictures that were each taken 24 hours apart by the HPWREN cameras at the Mount Laguna Observatory in San Diego County over a 3 year period.

Hats off to the cameraman who didn't move for 3 years 💀💀
Really, hats off to his wife who kept him supplied with tea and sandwiches for the whole time 😅
He did however take a bathroom break after the video was shot from which he still hasn't returned three years later.
@@reluctantconformistI googled the title and you'll never believe the weird website that came up when I accidentally put a space between the "E" and "L".
I'm pretty sure it's just his camera that didn't move, he just left it there
@@onesteeltank Correct and... I 'm pretty sure it was Mr Bean's new job assignment at the Observatory.
This works really well because of the overlaid graphics. Other attempts looked like crap because of all the cloudy days (as you are obviously aware). Congrats on inventing such a successful way of presenting the footage once you had it. Any good technician could acquire the footage with enough time, equipment and extraordinary determination, but it took the creativity of an artist to present it in an acceptably pleasing and innately informative way.

Oh wow!!!! All that time captured and put into a beautiful way the sun dance in the sky over the course of a few years!! Amazing!
Excellent!! Now I understand the analemma! The top and bottom are the solstices, and the intersection is the equinoxes! Cool!
No, the intersection does not coincide with the equinoxes. Watch the video again and you will see that the Sun passes through the intersection point on ~April 13 and August ~30. And then look where the Sun is on March 20 and September 22.
The equinox dates show the sun halfway between the two solstice ends. The loop intersection is related to latitude. All great observations!
Yeah, but why is it a asymmetric loop, instead of a straight line?

@@tatelyle1 Because of the ellipticity of the Earth's orbit and the difference between average and real solar time.
The top is when the sun is doing it Circuit North Center, North for six months where the sun takes a smaller route as it’s corkscrew back further south where everything expand further out south is the bottom part where the sun catches up speed to cover a huge land of area in a period of 24 hours, yes ladies and gentlemen, the Earth is not a spinning globe. It is a flat infinite topographical station airplane.
I glued a prism onto the sill of a south facing window then every two weeks marked the position of the yellow part of the spectrum on the ceiling with a little star glued to the spot. Now every day when the spectrum is on the line of my analemma I know it is exactly noon. You have to be rather obsessive to do what i did and more so to produce such a wonderful video.

It's a good thing that you chose a camera that can see the sun's shape due to sensor overload where the black spot represents the sun, which appears dark because of sensor overload, where the sensor struggles to handle the extreme brightness of the sun, rendering it as black or distorted in some cases. The amount of precision and patience of creating this project is surely worth it ❤️
Now I know what my solar tracking solar panel sees every year! I first thought I was wasting my time putting in the dual axis.

They also track the movement of the sun over the course of a day? right?

Emma is a magnificent artist, but she's a 1 track pony.
Wow a lot of time went into this. Sure highlights our short northern summers!
Now that was cool.
I've often wondered why it is drawn as a twisted loop.
Now I know 👍
The video doesn't explain this. The elongation is understandable - the Earth's axis is tilted, and the height of the Sun above the horizon changes throughout the year. Where do the "loops" come from? The Earth's orbit has a slight eccentricity, causing it to move faster for one part of the year and slower for another. That is, the duration of a solar day is different all the time - sometimes longer, sometimes shorter. We use the average solar day to measure time. The "loops" of the analemma show the difference between mean and real solar time - the so-called "equation of time".
I have been Watching the Sun for years and figured out its to the Left in Summer and Right in Winter. However, I did not realize it went Up and Down too! Nor did I know that it did a Crossover Loop!! Very very Educational Video on how the Sun Tracks on its Annual Route!!!
It depends also on latitude, dare I say. In extreme north or south places the sun could be beyond the horizon some days at a given hour, not that far from noon. I live in Costa Rica and therefore I'm very close to the equator. I see some changes in the time and position of the sun when it rises through the year but from my location wouldn't be able to do this because of the mountains, although it is possible from another place and way enough time.
The sun doesn't move. The changes in the appearance are due to the change of the earth relative to the sun, because the earth tilts on its axis.
Edit: I am speaking of the Sun in relationship to the earth. What I mean is that the earth is not stationary, and the sun does not revolve around it, nor circle above it. I have had too many conversations with flat-earthers, lately. Sorry.
@@annep.1905depends on what frame of reference you use... The frame in which the Earth is stationary is certainly not inertial; but it's still a valid frame of reference that we all use every day.
@@trueriver1950 Well, there's only one true frame of reference... but I suppose either way it's interesting to have that information. Of course, it's only really useful if you live in the same approximate latitude.
@traybern There would still be some seasons, because the earth also travels closer to the sun, and the cold air from the poles would affect the weather. But your response assumes that the earth's tilt is changing, which I am not sure is true.
Anyway, it matters little. This earth, probably, won't be around that long. In fact, I'm guessing that it only has a little more than 1,000 years before it is destroyed and a new, perfect earth is created.
This is awesome, deserves way more views

Which could mean: The sun will move across the sky for infinity.

@UnitTrace Even if it were just a mere 1000....
That piece of information is useless.
This is a great visualization to help me understand why summer & winter feel so long but then end so suddenly, and fall and spring seem so fleeting. The sun moves (relative to us ofc) so much faster during the fall and spring months
yep where i am spring and fall seem to last abt like 2 weeks in terms of temp lmao. but then theres like another 2 weeks of inbetween each so the other 40 weeks are relatively evenly split between summer and winter
Fantastic…and surprising. I always felt that winter sun went faster down somehow as the days shortened and the steep downward trajectory of this track proves it…notice also the sun is a bit lower before the shortest calendar day (Dec 21) in that little loop.
yep its why the earliest sunset is before the latest sunrise afaik. if practically stays in the same spot for 2 weeks lol
The sun doesn't go anywhere.. the earth moves.
@@tristantheoofer2 you must be joking. Every sunrise is before the next sunset which is before the next sunrise. If you go into the Arctic circle, there will be (at least) one day where the sun doesn't set at all. Is that sunset before the sunrise? Use your goddamn brain for 2 seconds. 🐵

The path it traces appears more like the infinity symbol. This could be why this shape was used to represent it.
Really great work!
The symbol was created by John Wallis in 1655 either at random or possibly as a corruption of a styling of the Roman numeral for 100,000,000.
Amazing work thank you very much !
I knew what the analemma is. Now I KNOW what the analemma is. Thanks.
Globes used to have analemma printed on them so you can determine clock time based on sun time.... we know why this happens.
The smoothness and consistency of the lens flare throughout the frames is something that you would obviously expect.
but seeing it with your own eyes is still surprising.
I’ve always loved these ever since I took a college astronomy 101 class and we learned about how this happens. We had to draw how the angle goes across the sky and at what angle depending on what month is was for our location as one of the a final tests on this topic.
I’m just wondering why people think that the earth is stationary. The solar analemma is caused by the earths elliptical orbit around the sun and its tilt on the axis of 23.5 degrees. And the Timelapse shows pictures of the days at the same relative time.
Our language is based on an Earth centred frame of reference. In General Relativity this is just as valid a frame of reference as any other.
It's a linguistic thing. Our almanacs still show times for "sunrise" and "sunset". We know what is meant and we don't quibble about it.
If you've ever asked a fidgety child to "sit still" on a moving train or in a moving car, I'm sure you really intended them to exit their the rear at -60mph?
Except when you're in a physics exam, please stop being pedantic.

Absolutely perfect thanks fir sharing this huge amount of diligent work!!
The best way to enjoy this IMO is to visualise the sun as static and the horizon moving up and down like the front of ship. Then you appreciate more that it is the Earth 'wobbling' through the seasons, whilst the Sun stays relatively in its place.
The only wobble is the one inside your funny little head, pal.
@@severiusbrandusa1413he's right though. The earth is tilted on its axis and that tilt doesn't rotate with earths orbit. That's the whole reason we have seasons. One half of the orbit has the northern hemisphere getting more sun and the other has the south getting more sun. That's why summer and winter are opposite one another across the hemispheres
@Coastal_Cruzer Sounds like your head is tilted too far to the left to know what's real and what's delusion.

I’m surprised that the camera wasn’t moved at all in 3 years, or a bug wasn’t in the way. Spiders unfortunately love my security cameras, and I once had a squirrel move one.
These are single frames taken over three years with an interval of 24 hours. Not continuous shooting.
@@andreytsyganov7321 I don’t see how that changes the fact that a human or animal couldn’t have moved the camera, or a bug or spider wouldn’t call the camera home and obstruct the view, for those three years.
@@jerickstudios596 What human? What if the camera was on the roof or on the balcony of the camera owner's house? Which human? What is the probability of a bug or a spider appearing in front of the camera at the exact moment of shooting? Why don't you assume that the owner of the camera periodically checked that nothing blocked the view?
When we first subscribed to Dish network they devoted a channel to a feed from their geo-sychronious satilite show what the Earth really looked like live. Fooling around one day I recorded 24 hours of this. The next day I played it back to see what I'd captured. It was the Earth, of course, with shadows and sunlight moving across the face our home planet, and it was very very boring.
I went to fast forward to end the recording and maybe see something interesting. I got more than I bargained for.
As Earth went nearly into shadow I could see the cresant of the sun bringing sunrise or sunset to different parts of the world. Then something I did not expect, the sun appeared on the other side of the Earth and passed behind it, just like we've all been taught, but here it was happening in front of me and it was eye opening and maybe even a little frightening, but more than that it was real! Like really real! Talk about "a moment of clarity"!
I'll never forget it.

Huge props to the Cameraman and his legs of iron

Thank you for making this
Awesome time lapse from the observatory. As usual, the more we know, the more questions we ask, and so here are a couple. 1) It is noticed that the time stamp is about 4:50pm to 5:50 pm PDT. Why not do this at 12 noon each day during maximum sun elevation? Is the hour difference sometimes due to daylight savings time and the late time due to show the geography? 2) The sun appears to move between 241 degrees and 282 degrees, giving a difference of 42 degrees. Shouldn't this difference be closer to 47 degrees (23.5S+23.5N)? Is this difference a parallax-type effect of taking the video from about 33 degrees North? Thanks, just being curious.
This is quite cool, thanks for spendiing three years making this happen 🙂
The stationary sun, moves so elegantly...
No it just moves
For some reason I thought this was going to be much more interesting to see when I clicked on it
Truly fascinating.
Impressive work!
Really good camerawork. Let's hear the flat earthers explain this! I wonder what latitude this is.
In San Diego
This is superb, I especially like the intro. Wow being alive and on a planet the right distance away, etc., it good eh.
Is this the same curve as plotting the point from a sun-dial pointer at the same time each day?
When you think about it, that is more or less what happens here: If you think of the camera as a camera obscura, the pinhole would represent the pointy bit of the sun dial, and the "plate" would represent the area the shadow is cast to. In a modern camera the focal point of the lens(es) would represent the pointy bit, and the photoelectric sensor the area the shadow is cast to.
(Sure, it wouldn't actually be the same, assuming the sun-dial is of the traditional type of flat plane with pointy bit standing straight up, since the projection would be a bit different, so you would get a slightly skewed version.)

I'm curious what the path would have been had you not followed Daylight Savings and kept taking photos at "4.40pm" instead of moving to 5.40pm.
The upper part of the curve will be shifted by 15° along the sun's daily movement. So in this case it would shift a little bit right and down.
@@SaMe-oi9ku Thank you
Amazing! Congratulations! God bless you! 😁👍
Great video. Inspiring. Thought provoking, see below. Keep them coming.
Q. 1 Would I be right, over time, I would expect the figure 8 travel, year on year, as the earth travels through seasons over the years. As you say the earth travels in an elliptical orbit around the sun?
The change would be tiny, but builds up over time, many years. A computer simulation extrapolating from the Analemma would better explain this.
Q. Also would the reason for the bottom heavy figure of 8 is because of the latitude above the equator. Perhaps another time lapse experiment could be done at the equator to show an even figure of 8. and one in the southern hemisphere. Or a lot faster a computer simulation from the input first analemma and other relevant factors.
On a related topic. I wonder if Stonehenge, In the UK, and others India, Egypt, Europe, Latin America had their megalithic structures so precisely aligned around the world, would have knowledge of this? As it would predict the best time for crop harvesting and cultivation, among uses.
The reason the figure 8 has a larger bottom section is a result of the earth's slightly oval orbit. Imagine an oval with a dot offset from the middle. When the earth is going around in an oval, the direction from the earth to the sun will not always be tangential to the outline of the oval. This is the reason for the figure 8. The reason for the slightly larger lobe at the bottom of the 8 is because the points where the oval is perfectly perpendicular to the path facing the sun are not symmetrical, due to the sun not being in the exact middle of the oval.
@@sodiumvapor13thank you for this excellent answer. I had thought it had something to do with the earth being a non spherical body.
@@sodiumvapor13 and as OP ponders, the elliptical orbit and the distorted analemma does indeed do the opposite down here on the south of the equator.
one goes further and can surmise that equatorial dwellers see it overhead, still distorted to one pole, with the unusual point that they have two winters per year at the two extremes of the solstice, and two summers at equinox...
and...
the distance travelled from equinox to solstice and back is not even... due to apogee and perigee velocities...
we in the south get long mild winters that drag on, as the sun stays low, only small changes every day, with rapid and fierce summers as we get closer and faster.
north getting long lazy mild summers with harsh fierce winters...
The first people to figure out agriculture must have had a reasonable amount of knowledge about the seasons, but aligning a megalithic structure like Stonehenge is probably easier than working out the best time to plant crops - you just have to get up before sunrise and move a log to point at where the sun comes up.
@@janTasita except... you have to do it EVERY DAY for lots of years... decades...
at least one year to know the solstices and equinoxes, a few more years to make sure, and what about if it rains?
got no clock... only idea of "time" is when that sun rises and sets. or moon. or stars... no way to tell what a "year" is until that shadow is right there again, and the weather feels the same. then theres the nuisance of the leap year messing things up every now and then...
you forget that everything you take for granted has been developed over a bloody long time...

Hello!
Great work!
But how did you convert yellow sun to black point? Photoshop? What graphical tools did you use for that?
Sensor overload as mentioned in the video.
@@makermarx I see. But how to see (make) this in image? Curves, filters, alpha?
@JustAGuy InBensalem We see black point, how did you get this as the Sun is yellow? :)
@@SlavBrothers it says in the video that due to sensor overload there was no data for that point hence black... Now we are not sure what kind of sensor was used, maybe something that captures luminosity or something and the centre part readings were probably outside the limits of the sensor
Think of it this way, you look at the sun for a second and look away at a wall or something, you will see a black circle due to "overloaded" luminosity on your retina
It was taken at the Observatory...where work is done for reasons Undisclosed to regular joes? Much Love and Peace 🤜🏼❤🤛🏿
Location?!
The acting in this video was just stellar.
Interesting that the summer and winter solstice happen right at the peaks of the shape, where the sun turns around. Very cool!
What is even more amazing is how those positions were identified by ancient peoples. Their intellectual curiosity drove them to measure it over the years, and was big investment in their time
@@danielmiller2886it is not amazing at all. Anything highly repetitive is easy to identify a pattern. The real time wasted is in diety worship and in this instance creating a master sun god.
This is so freaking cool
Our beautiful local Sun 😎.
A fascinating illustration (tracing) of the Sun doing its thing. Thank you!
It's interesting how this motion is attributed to the sun when it's actually due to the motion of the Earth.
Is it
That is because uniform motion is relative.
It is pretty much the same as traveling with a train. If the train moves uniform and without acceleration, it sometimes gives the impression to somebody in the train, that it is not the train moving but the landscape is moving by.
Of course this just an impression as we know that it is the train which is moving with respect to the landscape. But since motion is relative one can take both approaches and get exactly the same results. (This is eg. one of the results of Einsteins Theory of Relativity)
So by just looking at the system sun-earth, it is not important which is assumed to be stationary: the math works out in both ways, and after all what we see, is the sun moving across the sky in relation to the observers more or less fixed position on earth.
It is just when someone tries to come up with the math for all celestial bodies, that the math works out beautifully with a fixed sun and moving planets (and whatever can be observed in the solar system) while the other approach leads to really akward maths and no simple mechanism of why this should be the true nature.
This is why there were different models of the solar system in the past, which actually worked better then the in principle simpler heliocentric model (done with circles). It took a detailed data analysis done by Kepler to figure out the elliptical nature, which finally resolved to the simpler heliocentric point of view. And of course, after having figured out the distances and the masses of the celestial bodies it was very clear, that the sun represents 99% of all the mass in the solar system and hence it is the "stationary" object and everything else revolves around it. This was known long before a Foucault pendulum showed earths rotation directly the first time.
