Omega Sunrise

The photo above showing the Sun with the shape of the Greek letter Omega (Ω) was taken at sunrise from Playa del Carmen, Mexico on November 16, 2009. Omega shapes result from inferior mirages -- where the refracted image is below the object’s true position. As the Sun eases above the horizon (in the case of sunrises) its inferior mirage appears below and seems to reach upwards and join the Sun, creating the classic omega shape. On occasion, a green flash can sometimes be observed with this type of mirage, as the last vestige of the Sun’s disk dips below the horizon (in the case of sunsets). Note: though fascinating, as of yet a cocktail hasn’t been named in its honor.
