One of our references is
The Cloudspotters Guide by Gavin Pretor-Pinney, He also formed the Cloud Appreciation Society so I thought it apt to link to their site!
He describes lenticular clouds as a species of alto-cumulus clouds. They are orographic: ie formed when air is forced upwards as it goes over an obstacle such as a hill or Mountain. Apparently glider pilots refer to them as "lennies".
With the wind coming from the NW today a bunch of good lennies formed to our NW later in the day.
The classic shape is likened to a flying saucer. This one looks more like a cigar - or perhaps a roll-your-own!
Mt Imlay is certainly a mountain!
As the sunsets the colours got stronger.
