    This is what early astronomers thought the orbit was. They believed the earth to be the center of the universe, and couldn’t explain the strange orbits of the stars and planets.

      Or it was overcast on those days. 46/52 is far better than you’d be able to manage in my area.

    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.

    Then I try to think about space instead.

    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.

    Nnnnnnggggg!!

    This is highly infuriating! The sun keeps narrowly missing taking out the church spire.

    Neat. I naturally assume the very few apparent gaps are due to bad/cloudy weather on those particular days…

    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.

    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.

        That’s it! Thank you.
