Reflection subsun in Southern Finland
By Matti Helin
6th January, 2017, I observed a quite clear reflection subsun in the southern Finland.
Local time was around 11am. I looked outside and saw a nice sun pillar. Nothing special about it, but I decided to take a couple of photos of it anyway. I left outside rather hastily because there were clouds floating from north that would soon block the Sun.
I got the pictures and stayed for a while longer and saw the clouds running over the Sun, as I had predicted. Surprisingly, the pillar didn't disappear. I waited for a little while longer but the halo was stubborn. Then I realised, the source was not the Sun, directly, but its reflection! The sea is about ten kilometres away. It was most likely frozen, but wasn't yet covered by snow.
I also observed (probably) reflected crepuscular rays. If indeed so, it would probably be the first time ever that these two, refection subsun and reflected crepuscular rays had been photographed simultaneously.
