CHICAGO (CBS) — The sun did not have little babies overnight.
If you noticed a halo effect with two smaller sun spots beside the sun on Monday morning, there’s an explanation for that.
It’s called a sun dog, or “parhelion” — which means “beside the sun” in Greek.
It’s an optical phenomenon created when sunlight reflects off small ice crystals in cirrus clouds during extremely cold weather.
Basically, the crystals act like prisms, creating the visual effect.
