Unique optical phenomena puts on colourful show in Maritime sky

Like a rainbow turned to run parallel to the horizon, circumhorizontal arcs made an appearance in parts of the Maritimes on Thursday.
The unique optical phenomena is part of the halo family of effects.
The arcs are created by the refraction of sunlight by tiny ice crystals that comprise very high cloud in the atmosphere.
There were great conditions for that in the region Thursday, as high cloud spilled off a series of low-pressure systems and weather fronts to the west.
Here are a few of the pictures sent to me that shows Thursday's circumhorizontal arcs.
