This display came with a hot weather, the sun was up high slowly burning the living creatures on the field and the air was full of moisture. This is a common summer display when the sun is about 50° above the horizon. Fortunately I finished my job inside and drove ahead on the fields when the first patches of the parhelic circle started to appear.
The bigger white circle is named parhelic circle - a halo of multiple raypaths.
The smaller one is 22° halo with its tangent arcs.
It's also possible to detect a pair of parhelias on the parhelic circle. Their distance increases as the sun gets higher. 12:30-12:40 GMT+2, suns elevation 53.8°
A nice 22 halo and faint tangent arcs between the launch pause.
Around 06:30 GMT+2
