Did I spot Kelvin-Helmholtz?

I did not see this when I took the picture. I zoomed in and there it was.
is it true?  Is this a KH formation?

You may very well have Julia. Not a bad sky if you ask me, but at the same time, I also want to say no, because cirrus don’t usually form K-H waves, and instead it may just be some cirrus streaks in the shape of waves.

Just being a bit nerdy I had to check your statement about cirrus and KH, Gregory. The International Cloud Atlas (ICA) says:

Cirrus, usually of the species spissatus, sometimes shows mamma or fluctus.

This is the link (somehow I can’t add a link the way I used after the recent update of the website): https://cloudatlas.wmo.int/en/supplementary-features-and-accessory-clouds-cirrus.html

Nevertheless Julia, that does not mean I think you spotted KH. I agree with Gregory they “may just be some cirrus streaks in the shape of waves”.

I am sure there will be another occasion you will spot KH. Success!

Thank you for the info Hans!

[Julia Long]

Thank you Gentlemen!

I’ll keep looking up!
