In what is called a "rare optical illusion", three bright #suns were seen in the sky over a #Chinese city of #Mohe this week.
According to reports, not one, but three suns were seen in Mohe town of Tuqiang for about 3 hours -- from 6:30 am to 9:30 am.
This unusual event is a rare optical illusion caused by a natural phenomenon known as a '#sundog'. "They are frequently observed on a ring or halo around the sun," a report in Live Science said.
A sundog happens when sunlight passes through ice crystals in a particular way when they are suspended in the air.
"Sundogs are one of the most common types of #icehalo. They occur when light rays enter the side of an ice crystal and leave through another side inclined about 60 degrees to the first," the National Aeronautics and Space Administration (#Nasa) said.In what is called a "rare optical illusion", three bright #suns were seen in the sky over a #Chinese city of #Mohe this week.
