Infralateral arc - 14 July 2009

Today there was an unordinary sun halo in the sky. The sky had perfect clouds for this sort of phenomena. First I saw only circumscribed halo but later I noticed a small part of another one - the bigger brother arc.

You can see that above the roof in the right-hand bottom corner. Unfortunately, it was very faint and tiny part of infralateral arc. I managed to take only a few pictures and the show was over.
Bellow you can see the whole scenery taken with fisheye lens.
