Explanation: 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".

It’s almost as good as being there! Before APOD, if the eclipse was on the other side of the planet, you didn’t get to see it at all except for perhaps one photo. Now we get multiple exposures from all over the world. Great post!
Terrific! Thank You for your daily efforts for us here on FR!

HA...like I’ve been telling my husband....we don’t need to TRAVEL to these far out places...we can see more on our HDTV than if we WERE there! (I don’t much like flying!)
Thanks for bringing the link to the thread.
I’ll never fly again. Seriously.
That’s beautiful. Thanks for posting the link.
That’s spectacular!
