Greenland Ice Cap
| 1st October, a brighter and less windy day. Diamond dust and a low sun spin a parhelic circle around the sky. The elongated brightening on the right is a 120° parhelion.
Above the sun a weak upper tangent arc. Above that a circumzenithal arc from hexagonal plate crystals.
Plate crystals have created the two sundogs and contributed to the parhelic circle.
