I took the family for a day trip up to Tamborine Mountain last Sunday. One of the cool things I saw that day was a rainbow ring around the sun. This is an optical phenomenon known as a 22° halo and forms when sunlight is refracted in hexagonal ice crystals suspended high in the atmosphere.
The photo was taken with the camera pointing directly at the sun. The ring was observable with the naked eye and was even more spectacular than the photo suggests.
