Pileus clouds are also known as cap clouds or scarf clouds. They form over fast-growing cumulus or cumulonimbus clouds, in quiet or stormy weather, as a wispy, smooth band of clouds, curved like a contact lens.

$A Sun Dog is a Mock Sun is a Parhelion Sun dog is the nickname for a bright spot of color seen on either side of the sun in cirrus clouds. It follows the sun the way a dog follows a person. It is also called a mock sun because it imitates the sun and sometimes seems just as bright. The technical name is parhelion if theres one, or parhelia if there are two. Its a distant cousin of a rainbow. To get a sun dog, you need to have cirrus clouds, which are very high, and very cold, and made of ice crystals. The ice crystals separate the light into seven colors. Thats called refraction. Sun dogs are pretty and interesting and common. They simply tell you the clouds are high, thin and cold enough to be made of ice crystals.
