I've always been intrigued by "The Green Flash" - but had never seen it until making this video at the Very Large Telescope in Paranal.
I really enjoyed this film because it captures some of the magic and excitement experienced by amateur astronomers - and shows observing is more than just watching a static sky!
And here is a shorter version for those with lesser attention spans.
Pete Lawrence captured a great series of images during the sunset.
But this compilation really shows them off beautifully.
It also shows there was some blue light in there - an even rarer sight.
