I always follow the submissions in the forum for a long time now even if my understanding of german is not as accurate as when I was in school.
I am proud to submit here some of my images today as I once was amazed by some posted by Thomas Klein here (and at least in Flickr), about a nice display of Lowitz arcs in the year 2014, where we could see the Lowitz arcs crossing each other on the left sundog. When I discovered the result I got last April 4th, I immediately did think of that picture.
At this 4th April, we got a nice clear blue sky, until some cirrus vertebratus and other plane contrail came from the north and started to make some part of parhelic circle appear in the sky. So I manage to come back home and place my 2 camera on my roof windows and start shooting at the rate of 1 image every 10 or 12 seconds, in order to make good stackings. But I was far from expecting so much sharpness in the display, that was short in time: the clouds responsible of the halos cross the field of view in front of the sun in 15-20 minutes only.
I was outside taking care of my lawn as I was able to clearly see the lower part of the circumscribed halo with sunglasses on.
There is the time-lapse I made from those shooting images (with b&w rendering and colour rendering):
And here are some the best images stacked and rendered in order to see the Lowitz arcs, and the Wegener arcs (top left and right images) as it began before and then the Parry upper and lower arcs (bottom right edited to mark the names).
Sun was approximately 47° high above horizon.
I hope you will find them interesting to see too.
Bis bald.
