Strange Phenomenon (Sun Halo Over Johannesburg)
A perfect rainbow circle around the sun. Excuse the bad photo, I almost blinded myself.
It’s a phenomenon know as a halo (for obvious reasons) or a nimbus, icebow or gloriole. Today’s show in the skies over Johannesburg looks like a 22° halo specifically. It forms as sunlight is refracted in hexagonal ice crystals suspended in the atmosphere. Traditional belief has it that the halo is a harbinger of rain to come later.
If you see swallows flying through it then, I guess that would mean lots of rain is on the way?
