|Aureoles Small & Large
Top: Venus in the Pleiades surrounded by a blue centred and red fringed aureole ~0.4° radius produced by small water droplets. Image by Maximilian Teodorescu (site) in Dumitrana, Romania 3rd April '12.
Lower: A huge aureole around the sun produced in Hungary by sand carried from Africa. Imaged by Monika Landy-Gyebnar.
"On 5th April we had much African dust above Hungary, very early this year... I noticed it late in the morning and the diameter of the dusty disk around Sun was 18-20° radius at maximum size. Usually these African dusty airmasses come here from late April to late June, so this appearance is really early."

Droplets, sand, pollen, pigs with wings - all can produce aureoles. The larger the object the smaller is the aureole.
