Ahoj again Matěj, re: PHA. Thanks for the clarification. I knew you couldn't have meant the parhelic arc. Still, your parhelia are peculiar in a way, because of their large vertical extent, which is a consequence of wobbling plate crystals. There is also an analogy of this for subparhelia. Hopefull...

I like your delicate photos.

But what is a PHA? Is it elongated sundogs like these bright ones here?

By PHA i ment parhelion, sorry for bad grammar.

Thank you all! I have a very good feeling about the community here .

Hey all! :). On December 4th and 5th there was some few weak halos in Ostrava. I observed circumzenithal arc and parhelions.
