Venus green flash

Venus green flash by Colin Legg Photography

Many try to catch a green flash of the sun, shortly after sunset or before sunrise, when the sun is nearly entirely below the horizon. When just the barest edge of the sun’s upper edge is visible, you might – if you’re lucky and have a far, very clear horizon – see a brief flash of the color green.

But a green flash with Venus?

Yes. To the eye, Venus looks like a dazzlingly bright star, but, if you viewed it through a telescope now, you’d see Venus as a little disk. And, right now, you’d find that Venus is in a crescent phase – much like a tiny crescent moon – because it’ll soon pass between the Earth and sun. Its lighted side, or day side, is turned mostly away from us now. And if you had that telescope, and that far horizon, you might catch what Colin Legg of Australia has captured here: a Venus green flash. Colin told us:

It was taken Friday evening (February 17, 2017) with Venus around 2 degrees above Indian Ocean horizon. The telescope was a C8 2000 mm. The photo is cropped 2.5 x.

Bottom line: Crescent Venus and Venus green flash!
