Explanation:
If you went outside at the same time every day and took a picture that included the Sun, how would the Sun's position change? A visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at noon near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if the placement of the Callanish Stones has or had astronomical significance. The ultimate causes for the figure-8 shape of this and all analemmas are the tilt of the Earth axis and the ellipticity of the Earth's orbit around the Sun. At the solstices, the Sun will appear at the top or bottom of an analemma. The featured image was taken near the December solstice and so the Sun appears near the bottom. Equinoxes, however, correspond to analemma middle points -- not the intersection point. In two days there will be an equinox ("equal night"), when day and night are equal over all of planet Earth. Many cultures celebrate a change of season at an equinox.

@AlaskaWx @Climatologist49 What about the radius of apparent solar disc ? Along with refraction, like you wrote, it moves some artic circle phenomenon toward North.
I like to think about these sunrise and sunset questions with #analemma in mind.

@AkaSci
#NealStephenson the #SciFi author makes some use of them in his large interesting novel #Anathem

Which also has some echoes of what, perhaps, scientists might consider around this period of Administration of the USA.

I used to wonder why we don't set the time based on the sun being at it's highest point at noon.

I should probably stop asking this sort of question.

📸 Two Worlds, Two Analemmas
An analemma shows the Sun’s position at the same time each day over a year. Earth’s forms a figure-8. Mars, with a more eccentric orbit, creates a teardrop shape. The images were taken from Earth (2011–2012) and by the Opportunity rover on Mars (2006–2008).

@jbond You take the photograph of the celestial object at the same time of day over a whole year. The shape is produced because of the tilt of the #Earth in its orbit. The slightly irregular shape by the fact that the orbit is not quite circular but #elliptical. I made a simulated #analemma and posted it here some time ago using #Sellarium, to show what happens.

Taking some inspiration from today's #APOD, here I've used #Stellarium to simulate the apparent trajectory of the #Sun if it were photographed at the beginning of each month at midday where I live during this whole year. The characteristic figure-of-eight path is called an #Analemma. The individual frames were made into an #AnimatedGif using #Gimp.

Here’s a simulation of an #analemma for my location for the #Sun at midday on the first day of each month in 2025. Produced with #Stellarium and #Gimp.

Solar Analemma 2024

Explanation:
Recorded during 2024, this year-spanning series of images reveals a pattern in the seasonal drift of the Sun's daily motion through planet Earth's sky. Known to some as an analemma, the figure-eight curve was captured in exposures taken only at 1pm local time on clear days from Kayseri, Turkiye. Of course the Sun's position on the 2024 solstice dates was at the top and bottom of the curve. They correspond to the astronomical beginning of summer and winter in the north. The points along the curve half-way between the solstices, but not the figure-eight curve crossing point, mark the 2024 equinoxes and the start of spring and fall. Regional peaks and dormant volcano Mount Erciyes lie along the southern horizon in the 2024 timelapse skyscape.

@meteobures 🌄 ⏰ Ça y est ! Depuis le 2 à Bures-sur-Yvette, le #Soleil se lève de nouveau plus tôt que la veille. L'#analemme du Soleil y tangente l'horizon à 07:42 UTC tous les jours, et le ☀️ venait juste d'y franchir le point de tangence.
Le début de la fin des grasses matinées ?
Ce fut plus tôt en remontant au nord jusqu'au cercle polaire arctique ; se sera plus tard en descendant vers le sud jusqu'au tropique du Capricorne (hémisphère sud).
#astronomie #solsticeDHiver #grasseMatinée #analemma

Avez-vous remarqué ? 🌅🌇
Ça y est, les jours commencent à rallonger du soir ! C'est un bon prétexte pour marquer le coup : à l'instar du #solstice d'hiver, ou de toute autre fête de saison. 🥁
Comme le ciel s'annonce dégagé ces prochains soirs par ici, c'est l'occasion tant espérée d'un pique-nique au #Soleil couchant pour contempler le phénomène*.
Qui est partant ? 👀🕔

@meteobures ça y est ! les jours recommencent à s'allonger le soir par chez vous. Mais comme ils raccourcissent encore trop vite le matin, la durée du jour diminue encore jusqu'au solstice d'hiver. Vu depuis la latitude de Bures-sur-Yvette, 49° nord, l'#analemme de l'heure de coucher tangente l'horizon ouest.
