This agreeable lunar halo was visible from the United Kingdom's south coast on the 11th of February 2006. It was quite an eerie sight to see it hanging over the eastern horizon. This is a 22 degree halo, so called because wherever it occurs in the sky, it always appears as a circle with a radius of 22 degrees -- centered about the Moon (or the Sun). Although faint, the inner edge of the halo appears slightly reddened. The Moon wasn't quite full this night, though it appears so on the photo. This image has been enhanced by using techniques normally reserved for astronomical image processing.
