Very goody, Laurence. What is it in the sky of Maritime at Euston that almost parallels the overhead power lines?
G’day, sport, and welcome. Why/how clouds are there is exercising great minds as I write – here’s a couple of oceanic aspects

In general this Forum just wallows in day by day delights. But the first permanent thread in the Forum gives a link to the International Cloud Atlas (our bible) as its name suggests. And a popular link for optical events is
It’s often a tricky one, Ramona. I personally have trouble spotting those shadows. Your opinion is key because you were there!
I agree your clouds are high though I would have gone for Ac. They don’t look ‘tiny’ like grains of rice, possibly wider than the single finger test?
Since you like checking things out, you are aware of the ICA link in the first, permanent thread of the Forum –

Cc get 40 points because they are rare and fleeting I guess.

Hi ESB. I am surprised to be the first to comment your first picture has a cloud face, lower left centre – perhaps the best formed I have seen. What a contrast in colouring for the second. And well spotted as the mammatus are not so obvious in either.
Michael, Hygge is pleased with your initiating this thread, not least for the marketing of CAS. And I think you have asperitas to the T in your photos.
Hygge has never observed asperitas, but I seem to remember one photo in nearby Dorset, UK, so no excuses.
Hallo again, Ramona. In answer to your question, of course it is OK for you to start a thread. I think you have good skills and observations to offer, for our appreciation and discussion.
I agree your lonely cloud could be lenticularis species (and not pileus on the near looking Cu). But it looks too low and too large a cloudlet for cirrocumulus. So looking at the Cloud Classification it would have to be Altocumulus. But you have the keys
– was your lonely cloud wandering or hovering
– is there raised ground upwind
See The Cloud Collector’s Handbook pp 104/105 and 29.
28/28 vision
I have talked about my London Clock before. For the third time in 18 months the cumulus cloud disappeared recently and I was surprised to see 28 28 in the bottom line; that’s 28C and 28% humidity, a rare combination in Hampshire, UK.
One more time – look west an hour after sunset
