These are amazing photos of what is called "Green and Blue flashes at sunset otherwise known as Gegenshein [german for counter shine] I thought I
would share these images with my friends on ATS with permission of course from Mr. Stephane Guisard staff member from ESO [European Organisation for
Thank you Stephane

The Earth's atmosphere is a gigantic prism that disperses sunlight. In the most ideal atmospheric conditions, such as those found regularly above
Cerro Paranal, this will lead to the appearance of so-called green flash at sunset. ESO staff Stéphane Guisard has been chasing green flashes for
many years and has been able to capture them on many occasions.
These are only a few images of the many taken by Mr. Guisard
who has most graciuosly given me permission to post them.
The green and blue flashes are fleeting events that require an unobstructed view of the setting Sun, and a very stable atmosphere. These conditions
are very often met at Paranal, a 2635m high mountain in the Chilean Atacama Desert, where the sky is cloudless more than 300 days a year. Paranal is
home of ESO's Very Large Telescope, an ensemble of four 8.2-m telescopes and four 1.8-m Auxiliary Telescopes that together form the world's most
advanced optical telescope.

I hope you all enjoy this as much as I have.
