We do get some pretty skies
A solar frost halo - known as a 22 degree halo |
The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds in the upper troposphere (5–10 km (3.1–6.2 mi)), but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. Light is reflected and refracted by the ice crystals and may split into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting light between their faces, sending shafts of light in particular directions.
To produce these arcs, rod-shaped hexagonal ice crystals need to have their long axis aligned horizontally. In the foreground you can see the summer village where we live.
