That green flash again!

Sunset from North Island, 7 August 2016 - seconds before the disc vanished with a green flash
Sunset from North Island, 7 August 2016 – seconds before the disc vanished with a green flash

In the post of 24 July on sunsets on Bird Island, I mentioned the green flash that sometimes accompanies the disappearance of the last rim of the sun’s disc at sunset. On North Island on the evening of 7 August the six members of our myna eradication team, along with some volunteers on other environmental projects on the island (turtle and tortoise monitoring and vegetation management), had a social gathering on North’s west beach. At sunset there was some patchy cloud on the horizon but as the sun descended the disc was clear and the rim free of cloud. We watched the event but only one pair of binoculars was to hand. Most of us saw the green flash and the fortunate binocular user was able to see the movement of the green rim as the sun vanished.

Sunsets in Seychelles are always worth watching, ideally accompanied by bottles of the local beer, Seybrew. But on the occasions when the horizon is clear, the green flash can make its appearance without the aid of the beverage!
