Fogbow & Airplane - Maralinga, South Australia photographed by John Gilpin (site). ©John Gilpin, shown with permission.
A beautiful fogbow with at least three supernumeraries generated by the small droplets of thin mist. Faint traces of the bow continue below the horizon.
Fogbow colours, always pastel and diffuse, strengthen as the mist droplets increase in size and the bow approaches a rainbow.
A fogbow's supernumerary arcs have more saturated colours than the main primary bow and they deepen as the supernumeraries converge towards the glory at the antisolar point.
Supernumerary colours are also reversed - red hues on the inside.
