Explanation: An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day for one year. But the trick to imaging an analemma of the Moon is to wait bit longer. On average the Moon returns to the same position in the sky about 50 minutes and 29 seconds later each day. So photograph the Moon 50 minutes 29 seconds later on successive days. Over one lunation or lunar month it will trace out an analemma-like curve as the Moon's actual position wanders due to its tilted and elliptical orbit. Since the featured image was taken over two months, it actually shows a double lunar analemma. Crescent lunar phases too thin and faint to capture around the New moon are missing. The two months the persistent astrophotographer chose were during a good stretch of weather during July and August, and the location was Kayseri, Turkey

Is it analemma or analenema? I’m so confused.
Anyway, if you’re gonna have a double analenema, Turkey is a good place for it.

I don’t know why the moon needs an enema.
Seems like that would take a pretty fair sized hose.

And you know where the hose goes, don’t you? (Squeezing eyes shut, waiting for the inevitable chorus...)

If we have to see your anal dilemma better over Turkey than the US.

At first I thought it said "anal lemur," and I'm like:

Ana Lemma.
Isn't that the title of a novel by Dostoevsky? Or was it Tolstoy?
To: Verginius Rufus
No, it was Anal Emma by Stacey Abrams using a pseudonym.
