A view of the Sun on 12th July this year. Going against even my own advice of imaging as high up as possible to reduce atmospheric effects, nevertheless there was a reason - a sunset. Still, sunspots are clearly visible, even if not rendered at their best.
However, looking at the upper limb you may notice that there is some colour green, known as a 'green rim', and we're reminded of the 'green flash' effect sometimes seen under the best conditions right at the moment of sunset (defined as the moment the Sun disappears fully below the horizon). Almost any atmosphere produces a green rim but the elusive green flash requires such unusual conditions, stable air, that the UK is not known for.
But, for the last image, perhaps a second before sunset proper, there is some green and that may be the best my luck will stretch too.

These were taken from the viewpoint on Addington Hills (Shirley Hills if you're posh) and the trees highlighted are the beginning of the Chiltern Weald between High Wycombe and Amersham, about 33 miles away. In June the Sun sets right over a national grid sub-station known as the Amersham Main, a convergence (confluence, if you're from Shirley) of pylons clearly visible.
