This multi-day animation from Andy Berner shows geostationary satellite view of open cells forming in marine stratocumulus over the southeastern Pacific over multiple days.
This rotating actinoform cloud over the eastern Pacific actually has an eye.
This NASA Worldview image shows Kelvin-Helmholtz (K-H) billows superimposed on mesoscale rolls in stratocumulus. The mesoscale rolls are oriented E-W, while the much shorter wavelength K-H billows are oriented WNW-ESE (at least toward the bottom of the image where the billows are most clearly seen).
The mesoscale rolls likely align with the shear vector across the PBL, whereas the billows likely align with the shear vector across the inversion atop the PBL. These two shear vectors need not be parallel.
This MODIS Channel 3-6-7 image from Worldview shows ice clouds (orange) advecting over NW Scotland, and a dusting of snow (also orange) on the Scottish highlands
Unusual in this neck of the woods, these January POCs seen here are seen to be advancing on the Azores archipelago.
This is probably the best image of the sun one can find by looking at the Earth:
