🎵 Ooh, my lovely, glowing one, my glowing one When you gonna trace that line, Analemma? Ooh, you make the seasons run, the seasons run Got me followin’ the curve, Analemma
Never gonna stop, tilt it up, Earth's axial bind I always look it up, to see that figure-8 unwind My, my, my, ay, ah, wooh! A-a-a-Analemma
Come a little closer, sun, a-closer, sun Shining through the path in the sky, Analemma Keep it in geometry, you’re teasing me Tracing out the loop with such style, Analemma
Never gonna stop, tilt it up, Earth's axial bind I always look it up, to see that figure-8 unwind My, my, my, ay, ah, wooh! A-a-a-Analemma A-a-a-Analemma
When you gonna show to me, show to me? Is it just a matter of time, Analemma? Is it symmetry, symmetry? Or is it just a dance in the sky, Analemma?
Never gonna stop, tilt it up, Earth's axial bind I always look it up, to see that figure-8 unwind My, my, my, ay, ah, wooh! A-a-a-a-a-a-a-my, my, my, ay, ah, wooh!
Instead of making me think about space, the solar system or the universe… this just gives me an existential crisis, visualising how few weeks are actually in a year and how brief a lifetime actually is.
You know you spend way too much time on the internet. When your first though at seeing the top of the loop is that it's going to be a penis made out of the sun moving around.
So can someone who is more familiar with this subject answer, “Are these pictures taken at the same time of day with or without seasonal adjustments to time (Daylight Savings Time, etc.)?”
I understand why the sun would move vertically over the year due to the tilt of the Earth, but what causes the horizontal movement?
The Earth's orbit is an ellipse, not a circle, and therefore the Earth speeds up or slows down depending on where on its orbit it is at the time. In turn this means that the duration of the solar day fluctuates from day to day, from a bit under 24h to a bit over 24h and back.
So if you take a picture every 24h precisely the sun will appear to move horizontally a little bit on top of the expected vertical movement.
The analemma.
Then since that 8-figure is diagonal, the earliest sunset and latest sunrise are about two weeks on either side of the shortest day of the year. Same in summer with the latest sunset and earliest sunrise being a couple of weeks on either side of the longest day.
