Ok, I don't know that one. The Halot book is known outside of Finland for its spectacular images. He really should translate it to English and make some more money out of it!
The problem with this is that if I'd actually render it, everyone will claim that this can never be real.
I think lots of the more spectacular ones are fairly common in Antarctica, but for instance the Parry occurs perhaps once per year in Finland. So I'll confine myself to the more simple ones. Perhaps I'll add circumhorizontal and circumzenithal rings - they also seem to be reasonably common (i.e. more than ten days a year here).
It might be interesting for winter flying in northern Scandinavia, or over Antarctica. I have once seen the 46 degree halo in an aircraft before, but it was very, very faint. The super rare 120 degree halo would also be cool to see one day. I remember seeing a partial one from the moon a long time ago, together with the 22 and partial 46 and some common moon dogs!
The sun dogs are actually already done, it's what I referred to above as 'side sun' (I translated 'sivuaurinko' directly - that's the problem when you read not in English - you tend to pick up odd nomenclature...)
Like this:
The sun dogs are pretty clear in your two images above! Especially the top one where it's sitting on the 22 degree halo, or is that a cloud causing that effect? I meant that I look forward to seeing it while flying in FG Anyway, could they be made a little more triangular? With the edges on the 22 degree and 120 degree halos? They tend to stretch and fade out along the halo lines.
Are you also considering glories? These tend to be a much more common sight in an aircraft.

Edward
