Sun 46° halo - 25 April 2013

This morning was a little bit cloudy. During our journey to school with my daughter there was a 22° halo in the sky. I showed it to her and she liked it. But the situation dramatically changed after a while.

I took several photos with my mobile phone but its optical quality was poor for thie phenomena. During my return the sky changed. I could see a rare 46° halo, above was circumzenithal arc. Under them there was still 22° halo with one sundog on the left side and very slight another on right (not in the picture because it was taken later and this time was already disappeared). Around this smaller halo was upper tangent arc. I decided to go home quickly for my camera and took some pictures. Final picture consists of several one merged together.
