On very rare occasions, when the sun drops into the ocean there is a green flash. It is an optical phenomena that lasts for a second or two, caused by the reflection of the sun's light in the atmosphere.
My wife has seen the green flash in California. We have not seen it in Costa Rica. I have seen the green flash only once, and that was in the Cook Islands of Polynesia. Someone on our Solar Eclipse cruise there actually captured it in a photo.
When the sun disappears below the horizon, the sunset is not over, as I will show in the days ahead.
This week we are showing photos of San Xavier del Bac Mission, the White Dove of the Desert, outside Tucson, Arizona, on our Viva la Voyage travel photo site.
