A false sunrise in Alaska

A false sunrise in AlaskaThis is a fairly common event at certain times of the year.
Barrow Alaska is one of the northernmost cities on the planet. When the sun dips below the horizon on November 18 or 19 each year, the town experiences over two months of darkness. 

Nobody sees the sun again until it rises on January 22 or 23. But before the sun actually rises, the 4,000 or so residents can usually spot a fake sunrise, which is a weather-created optical illusion, a deceptive mirage caused by the frigid Arctic air bending the sun’s light so it just peaks over the horizon.
