Wow, those are really nice halos.
On the tricker arc area, isn't that a blue spot that we can see too ?
How high was the sun at the time of the picture ?

Re: Halophänomen 18.Jan.2015

Nice dispaly indeed. We had some interesting halos as well in eastern France this day, but no Lowitz arcs. By the way, on your gif: http://www.lightsearcher.de/AKM/A/AA0_180115_01f.gif Is it not the Middle Lowitz which is tangent to the Sunvex Parry arc, and the Upper Lowitz tangent to the Suncave A...

What an incredible halo display! Especially when you zoom on the 3 Lowitz arcs on the left parhelia, very neat, very well formed. What a day to remember !

Re: Halos + Parrybogen 17.08.2014

Hello there. Nice display indeed. The same part of cloud traveled 3-4 hours earlier on eastern France, where I am located, and we had also a nice display, but without Parry arcs.
I made a little timelaspe of stacked images from 13h03 to 16h03, where we can see the halos.

Grüsse.
