Australian Optics - Sunday 11th October at Bright, Victoria, Australia.   Rob Kaufman (atmospheric optics site) imaged (top) this late afternoon primary and colour reversed secondary rainbow. The secondary bow is always broader because rays forming it make a more glancing angle with raindrops and colours are then dispersed more widely. Below: A reddened primary competes with sunset lit clouds. Bottom image: Earlier at 4:40 he saw spectacular cloud iridescence.İRob Kaufman, shown with permission..
