APOD: Three analemmas for the price of one!
-
Solargraphy Analemmas[^] This picture uses a technique called solargraphy. It is a rather old method using a pinhole camera and slow reacting photographic paper: this allows the photographer to record the motion of the sun. This particular image was made by taking three one-minute exposures every day for a year, resulting in an analemma[^] at mid-morning, noon and mid-afternoon.

Nice APOD, thanks. It lifted my spirits this day. (Maybe I should go lift some, myself, later today.)
