Summary[edit]

Description
English: The total phase of the June 15 lunar eclipse lasted an impressive 100 minutes. Its entire duration is covered in this composite of a regular sequence of digital camera exposures, tracking the dark lunar disk as it arced above the Acropolis in Athens, Greece. In fact, around 270 BCE Greek astronomer Aristarchus also tracked the duration of lunar eclipses, though without the benefit of digital clocks and cameras. Still, using geometry, he devised a simple and impressively accurate way to calculate the Moon's distance, in terms of the radius of planet Earth, from the eclipse duration. A more modern Greek astronomer, Elias Politis titled this eclipse duration study and the accompanying youtube timelapse video "Acropoclipse".
Español: La fase completa del eclipse lunar del 15 de junio de 2011 duró 100 minutos y está cubierta en este compuesto fotográfico conformado de una secuencia regular de exposiciones de cámara digital siguiendo el disco lunar mientras formaba un arco sobre la Acrópolis de Atenas, Grecia.
Français : Phase totale de l'éclipse de lune du 15 juin 2011, qui a duré 100 minutes. Cette phase totale a été documentée par une série régulière de clichés suivant le parcours de la lune éclipsée tandis qu'elle passe au dessus de l'Acropole. En -270, l'astronome grec Aristarche a pu mesurer le diamètre de la lune et la distance qui nous sépare en mesurer le temps d'une éclipse de lune.
