A green beam appeared above the horizon in San Diego

When the weather is favorable during sunrise or sunset over an open sea horizon you can see the green flash, known as the green beam. Most often it is optical phenomenon can be observed in binoculars or a telescope, and only in rare cases — to the naked eye.

Not all green rays are the same. Evan Zucker has captured one unusual instance with the coast of San Diego April 15.

"I watched the sunset from point Loma when the ship took place against the backdrop of the setting sun. It was at that moment above the deck lit up bright green flash", — said Zucker.

Expert on atmospheric optics Les Crowley explained:

"It is a sign of a layer of strong temperature inversion. These inversions create a "duct". The sun's rays are reflected upwards and downwards and distributed over long distances, when fall into the "duct". The thickness of these layers is sometimes only a few centimeters. Could the ship somehow contribute to this? Unlikely, because the turbulence from the ship will be more fine-grained".
