Cloud Redux

Since some of you asked about that cloud I posted earlier:

Undulatus asperatus (or alternately, asperatus) is a rare, newly recognized cloud formation, that was proposed in 2009 as the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization.[1] The name translates approximately as roughened or agitated waves.[2]
