Wikipedia definition
2. Altostratus cloud​Altostratus is a cloud belonging to a class characterized by a generally uniform gray to bluish-gray sheet or layer, lighter in color than nimbostratus and darker than cirrostratus. The sun can be seen through thin altostratus, but thicker layers can be quite opaque. They can look similar to lower altitude stratus clouds. Altostratus clouds are formed by the rising of a large air mass that condenses into a cloud. They can produce light precipitation, often in the form of virga.
