Editing Stratus cloud (section)

=== Opacity-based varieties ===
Stratus fractus are not divided into varieties, but stratus nebulosus on the other hand, are divided into two. The '''Stratus opacus''' variety appears as a nebulous or milky sheet of the nebulosus species, but are opaque enough to block the sun from view.{{sfn|WMO|1975|p=43|loc=Description of Clouds}} '''Stratus Translucidus''' is another variety of the nebulosus species. These clouds are considered more thin than the opacus variety because this cloud is rather translucent, allowing the position of the Sun or Moon to be observed from Earth's surface.
