The sun had not fully set, but was just behind the ridge. I noticed this glow that looked like it was above the sun.
I cloud not tell if it was some effect like a sun pillar, or just a a lucky spot of clouds.
A bit later, it has moved relative to the contrail.
Later still. I stood on a low wall, so I was maybe 3 feet higher.
Last wide shot, seems to overlap the contrail.
