A whole patch of the sky went green at sunset this afternoon. By the time I stopped driving and found a vantage point it had diminished somewhat but was still visible at the centre of the shot above.
The phenomenon of the green flash refers to the sun going momentarily green at sunset and I guess this related as the sun's refracted light is being projected onto some clouds in addition to the red, orange and yellow light frequencies that are more usual.
In a less analytic sense - it was pretty weird!
Amazing! I think these are nacreous clouds - I've seen a lot of reference to their iridescent appearance recently. Caused by particularly cold high air apparently. Fab to see - lucky you!
ReplyDeleteThanks for the proper name for it, Belinda. So much easier to research it.
DeleteIs it linked to the Northern Lights?
ReplyDeleteThe same principle generates a rainbow. But the Northern Lights is, I think different being the upper atmosphere's reaction to ionic bombardment by the Sun. It sure is green too!
