    Ah, there are so many beauties above, but #122 and #123 from some time ago are very special Michael. I love the contrast of the bright reds with the darker blue background.

    There are a few very eye catching ones above. A sunset by Michael, Why Wait by Keelin with a misty scenery, a Nice Set of Molars (love it!) and a Spread Sheet by Ruth.

    You posted an ingenious Spread Sheet Ruth.

    The dances by Michael continue to amaze and I am curious Keelin, whether you already have an answer from Ian about the names. I remember you started on the Forum with your full name and then changed it.

    Yes all shapes and sizes, Ruth

    Ah, already a new volume. Ariel closed the former volume with a beautiful corona and a guarding sundog while Michael started with a faint halo in greys. Love it!

    Yes and what color has the rain?

    Here is another faint sundog together with some trails, of which one is blue.

    You may be right Shannon, but did you also consider cirrus intortus? I see a lot of similarities with the ones I can find on the gallery.

    You spotted lenticularis for sure Marie, except for the last one that shows tiny cumulsu clouds.

    Yes Marie, these are two very nice spottings. I agree with cirrus and stratocumulus for the first one. The second image shows undulatus in the upper part of the image and that must be altocumulus since cirrus don’t have a variety undulatus.

    Ah, Good Night 2023 and Hello 2024, thank you both Keelin and Ruth. And Michael as well for his remarkable reds in #114 and #115.

    I look forward to what surprises next year will bring from you all!

    Hello Susan, here are my thoughts.

    On your first image with the layer of altocumulus I see a hole. It is a fallstreak hole and the fallstreaks are already fallen lower. The bunch of fallstreaks is the rogue cloud (the white one with the decided twist) you mentioned.

    The second image is hard to judge because of the backlight. Maybe some cirrus or wisps of altocumulus. Hard to tell.

    I hope you like it.

    Thanks Ariel. Great halo display and yes a supralateral is not perfectly round. The 46 degrees halo is more rare, so usually it is a supraletral halo that you can see touching the CZA and that is also a difference between the two. The 46 degrees halo is a bit lower and clearly separated from the CZA in case the halos are visible enough. In you photo thuis is hard to see since the halos are a bit faint. Here is a link with the differences between the two halos: http://A 46 degrees halo or a supralateral halo

    Gail, here you can find a nice diagram that shows why it is called a 22 degrees halo: diagram

    Arielko you must have had a great day spotting this halo display. Love it. Yes, a sunvex Parry arc is there for sure. On your last image there is also a CZA and a UTA, but I am sure you already noticed. Maybe also a very faint supralateral arc?

    For some reason halo displays seem to be rarer over here. I have to send a ….

    Oh, wow, what an amazing cloud you spotted, Roshan. Thanks for sharing here. There is at the left in the first image clearly undulatus, which makes the cloud altocumulus. The curly ones are also altocumulus since they miss the striations of cirrus.  Maybe the curly part and the more plane and flat part are different clouds seen as one but at a different altitude.  This explains nothing about what’s happening but the lat image shows clearly fluctus or KH. They are caused by shearing winds at the level where they show up. The undulatus is also caused by shearing winds perpendicular to the pattern. It might be the same wind that causes the two phenomena at different altitudes in different clouds but both altocumulus. I must admit this is a bit speculative and I look forward to any other opinion. Anyway very nice.

    Hans
