Longest Day

This is as far north as the sun sets, taken at 21.41h. Compare with this blip from 27th April, where the sun is setting behind the chimney on the far left, and one taken in November from the same viewpoint, looking left (and a different chimney).  
The extra photo is after sunset, with just a glimmer of pink on the horizon, but the sky is still light at 22.39h.
