At sunset the pillar was difficult to pick out from the glare but as the sun sank further below the horizon it became more obvious.
At its best the sun pillar was only a few degrees high, but it lasted for 25 minutes before fading out.
During this time the sun moved 4.5 degrees to the right and 3 degrees lower, the images were taken roughly 4 minutes apart.
Although several contrails drifted through they didn't show an increase in brightness as they passed above the sun.
This shows the ice crystals responsible for the pillar were in the large thin veil of cirrus in the background.
