A colorful view of a storm system that is accentuated, as Jon describes, by the spots of rain on the car windshield. It adds to the "portal in time and space" vibe of this photograph, near Langfjordbotn, Finnmark, Norway.

A rare sighting of a reflection bow. Like the usual rainbows, this optical effect is formed by the reflection and refraction of sunlight shining from behind the viewer onto a shower of raindrops up ahead. But in the case of the reflection bow, the sunlight that forms it has been reflected up off a surface such as a smooth body of water behind the viewer. The bow appears at a different angle from the other rainbows. and with that, it is centered on a different point. However, the main bow and the reflected bow always meet at the horizon. This optical phenomena was spotted near Den Hoorn, Texel, Netherlands.
