Who Will Win

Lots of sunshine, increasing cloud - hope the sun wins out.
Perhaps someone who knows will tell me how/why the pink halo has appeared behind the sun. All I did was point and press... I have to say I rather like the effect.

Just finished work for 21 days - yippee! Not that I do much work these days, but nice not to have to think about others, in a work context, for a while.
