Light sabre in the Solway sky

I spotted an interesting feature last night. It hasn't photographed as well as I'd hoped but just above the bottom corner of the garage roof there is a vertical line. It remained steady until the Sun had gone completely over the horizon. It was clearly caused by the Sun illuminating cloud. I think it was probably a transparent layer of cloud and that the way that the Sun was shining from behind the lower clouds lit up a column through it but I couldn't easily detect the rest of the cloud. It could just have been a fluke that sunlight was lining up with a single cloud column but it didn't move at all whereas the strip of cloud above and right moved across to the left over time. It looks like it was probably a sun pillar caused by tiny ice crystals http://earthsky.org/earth/what-is-a-sun-pillar
