Venus corona
Article from Spaceweather.com:
Venus is so bright, it does things usually reserved for the Sun and moon. For example, Venus makes coronas. Photographer P-M Hedén of Vallentuna, Sweden, photographed this one on March 20th:
"We can often see coronas around a bright moon," says atmospheric optics expert Les Cowley. "This is rarer. The circular patch with a straw-colored rim is an aureole, the centre of a corona produced by light from Venus scattered by tiny water drops in thin cloud or mist."
"I've never seen one like this before," adds Hedén. "The Venus halo together with a crescent moon setting over our lake felt almost unreal." Images: #1, #2, #3, #4.
Look for your own Venus coronas tonight. The planet materializes in the western sky at sunset bright enough to see even before the sky fades to black: finder chart.
