I don't know how appropriate it is to post such a picture here, but I thought it'd be interesting to share it. I was at the top of Choc. There was a cloud only several meters in front of me and the sun right behind me. Because the cloud was moving fast, it was only for a moment that I saw my shadow projected on the cloud and something like a gloriole around it.
If anyone knows what is it called, I'd like to know.
