Skywatch Friday

Last Saturday while watching my granddaughter play baseball, I noticed this halo around the sun. Caused by sunlight or moonlight being diffracted as it passes through cirrostratus clouds that are usually at altitudes above 20,000 feet. Cirrostratus clouds are composed mostly of small ice crystals that spread out into a thin layer. They are sheet-like, and the sun and moon can be seen through them easily.
