Visibility II / V
As the frost period turned towards the end, a one-sided surface arc came off again. This time most clearly with such a small flat patch, where the very modest mutual case came off when they were first used.
Stacked (28 images, Figures 1 and 2) bounces clearly, much more modest in individual frames (Figure 3). However, it was easily distinguishable as a visual.
Those crystals had to be described at the same time, but the distances were at home despite the fantasies. The next day you were on your way, but the arches no longer stood out. However, I took close-up pictures in which the blade-like tip structure of the surface crystals that appeared on the arc surfaces stands out. In the reference image, a piece of the surface layer is peeled on top of the glove. Figures 6 and 7 are taken at slightly different angles from the same point on the surface.
