| Another image by Lesley Jennings showing the parhelic circle, a 22° halo and a 22° parhelion. Lesley took many images and some possibly show traces of Lowitz arcs. There was also an outer 46° halo, but no trace of tangent arcs or other halos from column crystals. |
| A parhelic circle and magnificently bright 120° parhelion, part of an extensive display seen by Lesley Jennings near Fraserburgh, Aberdeenshire, The 120° parhelion requires two internal reflections inside plate-shaped and oriented crystals. The brighter versions are probably the product of relatively thick plates or those of non-regular hexagonal form. |
