Though coronas can often be observed around the Sun and Moon, they're seldom noticed about Venus. Venus is the brightest object in the night sky other than the Moon, but it pales in comparison to our lone natural satellite. Look for a corona around our "sister planet" whenever thin clouds drift in front of it. Similar sized water droplets in clouds (generally mid altitude clouds) deflect the light of Venus resulting in faint but still detectable colored rings. Click on the image for a larger view.
