Explanation: Many think it is just a myth. Others think it is true but its cause isn't known. Adventurers pride themselves on having seen it. It's a green flash from the Sun. The truth is the green flash does exist and its cause is well understood. Just as the setting Sun disappears completely from view, a last glimmer appears startlingly green. [continued]
The green flash is an optical phenomenon that occurs at sunset or sunrise when a green spot is briefly visible above the upper rim of the sun's disk. It is caused by the refraction of sunlight in the Earth's atmosphere.
To capture a good picture of the green flash, you will need a camera with manual settings and a tripod to keep the camera steady. You should also choose a clear day with minimal atmospheric disturbances and position yourself in a location with an unobstructed view of the horizon.
The best time to see the green flash is during sunset or sunrise, when the sun is close to the horizon. However, the conditions have to be just right for it to occur, so it may not be visible every day.
Yes, there are often other colors involved in the green flash, such as blue, violet, and even red. These colors can be seen as the sun sets or rises and the light is refracted in the atmosphere.
The green flash is not necessarily rare, but it can be difficult to see. It requires specific conditions and a clear view of the horizon, so it may not be visible every day. However, with the right preparation and timing, you can increase your chances of witnessing this beautiful phenomenon.
