Unknown halo in Germany

This archive picture photographed Dieter Klatt on october 25th, 1996 in Oldenburg (North Germany). It shows an upper unknown arc with faint 22° halo, right parhelia and a eft fragment of parhelic circle.

  1. The quality of the the photo is not very convincing. Claudia, can you give the sun elevation? And what about the lens? Some kind of wide angle thing that you screw on the normal lens?

    I don't see parhelic circle, only short tail from right parhelion.

    About the Lowitz - Parry connetion. Untill year 2000 we have 9 observations of Lowitz arcs without Parry arcs (many of them photographed). The Lowitz arcs from plate crystals should not have anything to do with Parry arcs, their co-occurrence is only coincidental.

  2. It's definitely worth knowing this observation. It's just that the thing looks so odd and the photo is not exactly the top notch quality. But now as you gave the sun elevation, we can perhaps say something more definitive about it on the basis of simulations. I'll see about it later.
