Increase your chances of seeing the green flash at Sunset
The real sunset phenomena called the “green flash” is often cited but seldom seen. It can manifest itself to a one-time visitor while eluding local residents for decades. In this way, viewers become divided into the visual “haves” and have nots”.
To increate your chances for becoming a “have”, start watching a few moments before sunset on clear, cloudless days when waves are small and the Sun remains yellow almost to the horizon.
