On 16th April 2012 at Sydney’s Royal Easter Show, I saw this unusual phenomena in the western sky.
It is a Sun Dog, they occur when sunlight is refracted by ice crystals, they are always 22 degrees from the sun. Despite the dark appearance of the photo, the sky was really quite bright, the Sun and sun dog are much brighter than the sky, the extremely short exposure indicates this. Camera was a Canon 5d mk ii, ISO 200, f20 1/2700 sec, taken 16-Apr-2012 16:21AEST.
