Extravaganza! Look at these amazing lenticular clouds over the Ionian Sea just east of Mount Etna!
According to witnesses the show lasted for almost 10 hours! I love beautiful standing lenticular clouds!
Finally an amazing timelapse of an impressive altocumulus lenticularis duplicatus clouds over Mount Etna , Sicily from October 2 2014:
