Look up! Circumhorizontal arc!

In recent years, I think I look at the sky more often than I used to. Have seen some interesting things, such as a strange equilateral triangle cloud, iridescent clouds, numerous parhelions. This time my husband was with me and had his camera. Wikipedia helped me determine that others know this phenomenon as a circumhorizontal arc. https://en.wikipedia.org/wiki/Circumhorizontal_arc

There are eleven (I think) kinds of clouds
I love watching clouds. It's a permanently changing landscape available year-round, even at night.
I have a book on clouds somewhere and IIRC, there are eleven kinds of clouds.
The first ten were determined by some Victorian scientist.
Number eleven is modern: jet contrails are a kind of cloud.
That's a lovely picture. I haven't seen one of those.
I have seen rainbow rings around the full moon. Lovely and unearthly.

Light & Color in the Open Air
It is exciting to see these things, but all the better when it can be seen with others.
When I was a child there were not enough books to read in my house. I used almost try to desire into existence something to read. Thus, I tried to read whatever came into the house. When I was about 10 or 11 a book called "The Nature of Light and Colour in the Open Air" by M. Minnaert https://www.abebooks.com/servlet/BookDetailsPL?bi=30837361653&cm_sp=SEAR... appeared, brand new, from nowhere that I could fathom. Well, I gave it a try. It was full of equations that mean nothing to me even to this day, but it did give me the motivation to look for the phenomena that were illustrated. I ended up writing my name inside the cover and taking with me everywhere I've lived since.
That book is around here somewhere; I should look for it. I should see if my son wants it. Ironically my son is in optics, though at the level of photons rather than of atmosphere. I should pass the book on to him as a "classic."
