Altostratus
What is Altostratus?
The base of the altostratus clouds are higher than ordinary stratus clouds are flat sheets, the base of which is higher than ordinary stratus clouds. Similar stratus, this plain layer of cloud covers the entire sky.
Altostratus can be with, gray, or blue-gray uniform cloud sheet that may, like stratus, blanket an area as large as hundreds of square miles. It is generally thin enough that a dim outline of the Sun (called a “watery sun”) or Moon can be seen through it. Sometimes, however, it is thick enough to entirely block our view of the Sun or Moon.
