Green Flash

Mixed media (metal Geodesic Sphere, PET bottles, optical fibre, LED light source)

The Green Flash is one of those naturally occurring optical phenomena (similar to the Aurora Borealis) that captured my attention and imagination as a child. Later, when living in Australia in my 20s, I spent many sunsets (and occasional sunrises) attempting to capture the elusive green flash with my camera. Green flashes and green rays sometimes occur right after sunset or right before sunrise because the atmosphere can cause the light from the sun to separate into different colours. When the conditions are right, a green spot is visible above the upper rim of the disk of the sun. The green appearance usually lasts for no more than a second or two. Very rarely, the green flash can resemble a green ray shooting up from the sunset or sunrise point. Green Flash is an amalgam of processes, materials and structure: a monumental geodesic sphere from which radiate 1820 empty PET bottles. Each bottle is illuminated by a single fibre optic cable. At dawn and dusk 1820 illuminated bottles slowly morph through the colours of a rising and setting sun, momentarily flashing hues of green
