This photograph, taken at Jersey Airport, Jersey, shows a sun pillar on the point of sunrise. The sun pillar indicates the presence of Cirrostratus and is formed by the reflection of sunlight from plate-like ice crystals. The Cirrostratus is very thin and featureless with no distinct detail, and thus is the species nebulosus. A few small patches of Cirrus are also in the sky. Reports indicate that sun pillars were visible over southern England, UK and northern France. A small patch of shallow fog is visible on the runway.

High pressure of 1 030 hPa was centred over north-east France, with weak fronts over the eastern Atlantic.
The ascent from the nearest upwind station at Camborne, England, UK (WMO 03808) shows a shallow moist layer at around 10 800 m, the likely height of the thin Cirrostratus cloud.
A Sun pillar is a luminous pillar of light that extends vertically above the Sun. It forms as a result of the reflection of light off plate-type ice crystals. This example shows a Sun pillar shortly after sunset.

Columns of light extending upwards from terrestrial light sources may sometimes be seen at night during very cold weather. In this case, the air temperature was –28 °C and the light pillars were formed by the reflection of light from ice crystals in the air. The view here is facing towards Cambridge Bay Airport (CYCB), Nunavut, Canada.
