ParticipantMorning Rebecca, My thinking is yes to undulatus (albeit it rather short ‘cloud streets’!) but not radiatus. To be radiatus the undulatus lines need to be long and appear to converge to a point near the horizon, giving the appearance of fanning out towards one from that point. Any other views? I’m happy to be informed and corrected! I love the way the undulatus clouds are reflected in the water below, which in turn has its own undulations. Kind regards, Gail

ParticipantHi Kreable, When sunlight shines through the ice crystals of high Cirrostratus clouds, it can be refracted into bright rings of light known as halos. My thinking is that this is a non-quite-so bright moon halo, with the bright moonlight shining thru the water droplets of your fog, and it has formed a 22 degree moon halo. I think I can also discern a smaller, inner (and rarer) 9 degree halo. Any other suggestions? Kind regards, Gail

ParticipantI too think they are contrails. Mabye a couple of RAF jets doing a sunset aerobatic manoeuvre together. The sun is setting in this photo so I thought about how the clouds are being illuminated. Have a look at the thin wisps of cirrus around the contrails… both they and the contrails are pink. An explanation for this is that the cirrus and contrails are high up in the atmosphere and are being lit on the underneath by the setting sun rays which, having further to travel, are the longer wave red rays. The much lower stratocumulus are completely black as they are in shadow, although if you look carefully you can see the distant stratocumulus clouds do also have a pink tinge on the top of the clouds where they are also catching the last rays of the setting sun. Maybe?

Participantmammatus not mammals! Dam autocorrect…… :(

ParticipantYes, these are mamma (or mammals) which hang from the end of a cumulonimbus storm cloud which has passed.

ParticipantHi, IMHO I don’t think it’s Volutus… it doesn’t appear to be rolling and volutus is a roll cloud. It may just be a long cumulus cloud but definitely with virga.
Cheers

ParticipantHi Marie, beautiful clouds indeed! I think the first 2 photos, especially the second one, are Vertebratus. Happy to be corrected.
Not sure about the others but very nice indeed.
Kind regards, Gail

ParticipantLovely indeed… I think it is Altocumulus Floccus. I’m unsure whether the little ‘silkworm’ in the middle right of the picture can be classed as Vertebratus.
Kind regards,
Gail

ParticipantHi Gail,
Yes there is. Go to your App Store and download the Cloud Appreciation Society Cloud-a-Day app. It has an AI cloud identifier function which is very useful.
Kind regards,
Gail

ParticipantThanks all, especially Hans for the diagram.

ParticipantAhhhh… thank you so much. I was thinking of geometric angle degrees not celestial astronomic degrees. It now all makes sense… I should have twigged being a (very) amateur astronomer.
