Details:
Around the winter solstice, if I step outside my front door in Lochearnhead, Scotland, I can see the Sun rising from behind a large rocky outcrop, the lower summit of Stùc a' Chròin.
Its just the right shape and distance to cover the Sun, like my own solar eclipse, every Christmas. Other than a sunrise though, can any eclipse phenomena be seen? It's pretty tricky to catch a clear sky that time of day in December, but this year I was lucky. I took a burst of pictures hand held with a telephoto just as the Sun appeared, and amazingly, a pink prominence could be made out. Just to be sure, I stacked the pictures in a sequence to show the prominence tracking to the right as the Sun rose.
Confirmation came from an Australian National Solar Observatory (NISP) image just 10 minutes prior. I have added it below in the stack.
It's pretty tricky to see prominences without special filters, and since most occur near the Sun's equator, the geometry is wrong for one to appear at the Sun's upper limb. This very high latitude prominence was a pure fluke - the sequence was also helped by the rocky summit lacking grass which would scatter too much light.
